An energy pyramid shows how energy flows through an ecosystem. An image is provided. Each level gets only about 10% of the energy from the previous level. If living systems follow the law of conservation of energy, where does the remaining 90% of the energy go?
A. A It is used by decomposers during decomposition.
B. B It is converted into heat and energy for life functions.
C. C It is converted to matter during digestion.
D. D It is used by organisms in the lower trophic level.
Answers
Answer:
b
Explanation:
some is used, some is wasted by giving off heat, being excreted, etc
The statement (B) is correct. It is converted into heat and energy for life functions.
What is an ecosystem?An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
Moreover, an energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level. The energy in an energy pyramid is measured in units of kilocalories (kcal).
Therefore, a pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.

2. Energy moves around this ecosystem through a food chain. Producers (plants) use sunlight to produce energy through photosynthesis. This energy is then transferred to herbivores (rabbits), which are eaten by carnivores (hawks). Energy is lost at each level of the food chain through respiration and other metabolic processes, so the amount of energy available at each level decreases.
3. If a disease strikes the snake population, the population of hawks and rabbits would be affected. If the snake population declines, there would be fewer predators to prey on the rabbit population. This would cause the rabbit population to increase, which would lead to an increase in the hawk population as they have more food to eat. However, if the disease is severe and the snake population declines too much, there may be a shortage of food for the hawks, causing their population to decline as well.
4. If the rabbit population suddenly doubled, the effect on the grass would be negative. With more rabbits, there would be more grazing pressure on the grass, leading to overgrazing. Overgrazing can lead to a decrease in grass biomass, which can negatively affect other organisms that rely on grass for food and shelter. Additionally, with less grass available, the rabbit population may eventually decline due to a lack of food. This would cause a chain reaction that could lead to the decline of other organisms in the ecosystem.
7. So if a disease stroked the snacks population than the effect on hawks would be that they would feed off a different food source, such as the rabbit. The rabbits population would decrease and soon enough the hawk population would decrease because of the competition towards food. This happens because snakes are secondary consumers and hawks feed off both rabbits and the snakes to balance the populations. If one disappears or decreases than the hawks would aim toward the animal that has a bigger population, the rabbit. Making the rabbit population leading towards less food all around.
8. If the rabbit population doubled than the grass would decrease or would die. This would happen because there is to many consumers and the grass can not keep up with how much it is giving out. This would also lead to a decrease to the rabbit population making the population really low or back to normal, depends on how quickly the grass grows.
What do you predict might happen if someone introduced a new species that could eat large amounts of algae at a rapid pace, outcompeting other species already present? Describe what you think might happen, making sure to specify how at least three of the organisms that might be affected and giving a detailed explanation for each organism. Make sure to include in your answer at least one organism that does not eat algae.
Answers
Answer:
Small fish, crustaceans, and water-dwelling insects eat algae, so they are going to be affected if an new species is introduced and is water based, also the new species its the algae at a rapid pace, a bunch of organisms will be in danger because some of the organisms eats algae as a primary source of food. If there is something that can make this species go extinct for sometime until it is possible algae can grow as fast as they eat it, then there would be a bunch of sea creatures/organisms affected by this huge change. Not only will the small fish, and other sea creatures/organisms will be affected but it'll also disrupt the ocean food chain, including us human! Because we eat fish, some people depend on algae because if the algae kept getting ate up by this "new" species EVERYTHING else would be also disrupted. Microscopic animals wouldn't have enough food, fish wouldn't have enough oxygen and plants would lose some of the carbon dioxide they need to grow, so these organisms DEPEND on algae for their LIFE!

4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.
Answers
PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.

Adaptations are features that were produced by natural selection to increase the of an organism.
Answers
Adaptations are features that were produced by natural selection to increase the chances of survival of an organism.
According to the theory of natural selection, features that may be passed down enable animals to adapt to their environment more effectively than other members of their own species.
What is Natural selection?Natural selection is indeed the variation in individual survival and procreation brought on by phenotypic variances. The evolution of a population's heritable features across generations is a fundamental mechanism of evolution.
Natural selection is a process in which more environment-adapted organisms tend to thrive and reproduce more frequently than less environment-adapted ones. For instance, birds and snakes occasionally consume treefrogs.
Hence, traits that may be passed down allow animals to adapt to their environment more successfully than other members of their own species, in accordance with the principle of natural selection.

Answers
Answer:
The amount of substance present in a certain sample can be calculated through the equation,
A(t) = A(o)(0.5)^(t/h)
where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.
For a substance to at most 50% of the original amount, we get the half-life value.
At/Ao = 0.5 = 0.5^(4.5/h)
h = 4.5 billion.

Male lions and female tigers can produce offspring. Thus the correct option is A.
What is liger?The offspring of a lion and a tigress is called a liger.
Although they rarely meet in the wild, lions and tigers are still so closely related that they are able to interbreed, and in captivity they occasionally do. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.
