Answer:

Food webs are more complex than food chains, yet equally as useful in understanding the processes of ecological communities.  A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before.

Explanation:

Food webs in an ecosystem involves the combination of two or more food

chains. This involves all the relationship an organism has with the others.

This makes the food web complex.

Food webs have different types of organisms present which ranges from

plants which are regarded as the primary producers to animals such as Lion

which can be regarded as a Secondary/tertiary consumer in the ecosystem.

The occasional change in the geography and seasons in the ecosystem

also makes it very complex as some animals exhibit different traits when

subjected to certain conditions. This makes analysis of energy flow and relationship sketchy to determine.

water moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again

According to the research, the correct answer is that the flow of energy is part of the rock cycle through the solar energy that reaches the Earth and the internal heat of the earth both drive and provide energy for processes of the Cycle.

They are the geological processes or transitions of material that rocks go through to become one of the different types of rocks:

In this sense, the two sources of energy for these transformations are the sun providing energy for sediment consolidation processes such as erosion and transport to form sedimentary rocks and internal heat from the earth providing energy for processes such as subduction, melting and metamorphism that occurs in igneous and metamorphic rocks.

Therefore, we can conclude that according to the research, the flow of energy allows processes such as erosion, melting, metamorphism essential for the rock cycle.

Tigers have the ability to coexist with their own predators like brown bears, leopards, etc. In this condition, it is the risk that these predators may threaten the tiger species. Therefore, it is required to construct a special habitat for tigers where they get enough resources without any threat.

An ecosystem may be defined as a place or area where members of different species live together and interact with one another for the purpose of food, shelter, and space.

The strength of the above solution is that the population of tiger species will be maintained in near future, but the limitation is that here we provide an artificial habitat for the tiger. Now, it depends on them to reside naturally or not.

The flexibility of spider silk determined by the structure of its molecules is quite strong.

The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.

The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.

what are the choices

Explanation:

photosynthesis is a way that plants make their own food.

Explanation:

Euglena and Trypanosoma are placed in different classes because they belong to different taxonomic groups based on their distinct characteristics, evolutionary relationships, and overall organization. The classification of organisms is determined by their shared similarities and differences, allowing scientists to group them into various hierarchical categories.

Euglena and Trypanosoma belong to different classes due to the following reasons:

1. Morphological Differences: Euglena is a unicellular, freshwater protist that possesses a characteristic whip-like tail called a flagellum, allowing it to move and propel itself. It also contains a photosynthetic pigment called chlorophyll, enabling it to perform photosynthesis. On the other hand, Trypanosoma is a parasitic protist that causes diseases such as African sleeping sickness and Chagas disease. It possesses a single flagellum but lacks chlorophyll and cannot perform photosynthesis.

2. Evolutionary Relationships: Classification takes into account the evolutionary relationships between organisms. Euglena belongs to the class Euglenophyceae, which includes various species of photosynthetic protists. They are considered to be a diverse group that originated from a common ancestor. Trypanosoma, however, belongs to the class Kinetoplastea, which includes various parasitic flagellates. These organisms are not closely related to Euglena, indicating a distinct evolutionary history.

3. Biochemical and Genetic Differences: Euglena and Trypanosoma also differ biochemically and genetically. They have distinct cellular structures, metabolic pathways, and genetic compositions that contribute to their unique characteristics and lifestyles. These differences further support their classification into separate classes.

By considering these factors, taxonomists and scientists classify organisms into appropriate hierarchical categories, ensuring that organisms with shared characteristics are grouped together while differentiating them from organisms with distinct features. The placement of Euglena and Trypanosoma in different classes reflects their distinct biological attributes and evolutionary histories.

Answer:

Explanation:

Euglena and Trypanosoma are both unicellular organisms that belong to the kingdom Protista, but they are placed in different classes because they have different characteristics and lifestyles. Euglena is a photosynthetic organism that can produce its own food using sunlight, and it has a structure called a chloroplast that contains pigments such as chlorophyll. It also has a flagellum, which it uses to move around in its aquatic environment. Euglena belongs to the class Euglenophyceae, which includes other photosynthetic unicellular organisms that have similar characteristics. On the other hand, Trypanosoma is a parasitic organism that feeds on the blood of its host, and it does not have the capability to photosynthesize. It moves by using a single flagellum and has a unique structure called a kinetoplast, which contains DNA and other important cellular components. Trypanosoma belongs to the class Kinetoplastea, which includes other parasitic unicellular organisms that have similar characteristics. Therefore, Euglena and Trypanosoma are placed in different classes based on their different modes of nutrition, locomotion, and other morphological and physiological characteristics.  

The operating statement for the retina at various light levels above is E. All of the above

The eye is the sense of sight that provides us with visual information. The eye sees an object through light that is captured by the cornea which is then received by the retina.

In the retina there are nerve cells that are sensitive to light. Retinal stem cells function to see dim light, rod cells see bright light and color. Retinal ganglion cells will cover messages from rod cells and cone cells and then send information to the brain via the optic nerve. The brain will respond to the impulses given and translate them into images.

The retina has operations at various light levels which are as follows:

For a given level of ambient light, the central ganglion cells respond proportionally to a small point of light over a range of about one log unit intensity. Through an adaptation mechanism, the ganglion cells in the center can dynamically encode the brightness level in the center in the range of 6 log units of ambient light level. Ganglion cells generally do not report absolute light intensity, but instead encode the difference in relative intensity between center and surroundings. Interactions in the outer plexiform layer play an important role in modulating the photic sensitivity of ganglion cells.

Answer: Overgrazing, overfishing, and forest fires

Explanation:

Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.

According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.

The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.

Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.  

Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.

Explanation:

reason why is because blowing through a straw demonstrates air so when you blow it against sand or dirt it blows pieces of soil or sand away and in different areas.

Blow into a drinking straw over the sand which demonstrate wind erosion using this model. So, the correct option is (B).

Wind erosion is defined as the natural process that moves soil from one place to another by wind energy which can cause significant economic and environmental damage.

It is a major cause of land degradation in arid and semi-arid grasslands, which is one of the processes leading to desertification. Significant wind erosion occurs when strong winds blow on light textured soils that have been heavily grazed during periods of drought.

It can happen anytime and anywhere when the wind blows which can happen in any area where sand or soil is not compacted or is of fine grained nature. Wind erosion not only destroys the land by drying out the soil and depleting the land's nutrients but also results in air pollution.

Thus, blowing into a drinking straw over the sand which demonstrate wind erosion using this model. So, the correct option is (B).

c-The water is under pressure naturally and no pump is needed.

Explanation:

Water from Artesian well is the water is under pressure naturally and no pump is needed.

A well from which water flows under natural pressure without the need for pumping is known as an artesian well.

It is excavated or drilled whenever a gently sinking, permeable rock layer (such as sandstone) collects water at a level higher than the ground surface at the well site.

Water goes down into the aquifer (water-bearing layer) at the outcrop, but is blocked from escaping by impermeable rock layers above and below it (such as shale).

Water is forced to the surface of a well drilled down into the aquifer by the weight of the water (hydrostatic pressure) the pressure for the continuous up flow is maintained by the continued penetration of water into the aquifer at the intake region.

The ability to collect water is what distinguishes artesian wells.

The water is under pressure naturally and no pump is needed.

Pumping water isn't essential because there isn't any pressure in the water.

Answer:

Plants and animals took up different evolutionary pathway millions of years ago.

In the prebiotic earth, the CO2 levels were insanely high, and the solar input was quite high due to which the initially evolved cells were photosynthetic , so that they can harness the solar energy, and because they need a carbon source, they relied on the Carbon from CO2.

In this process, the atmospheric gaseous content changed, as predecessors of plants gave out Oxygen over millions of years.

Gradually , the atmosphere was now oxygen rich and hence predecessors of animals evolved a mechanism to utilise this oxygen , and as a byproduct started releasing CO2.

Over the next years , these two diverse groups specialised and hence , became increasingly different.

There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.

The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.

The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.
