Compare AND contrast primary and secondary succession.
Answers
Answer:
Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Explanation:
Answer:
The basic difference between primary and secondary succession is the presence of soil. When primary succession begins, soil is not present; in the case of secondary succession, soil is already in place.

(Both Types of
Grasslands)
(Temperate

Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Why are the magnetosphere and plasmasphere important to the biosphere? Select all that apply.
They contain all of Earth’s water in the form of solid, liquid, and gas.
The biosphere would not be able to survive without the protection of the magnetosphere and plasmasphere.
Without the protection of the magnetosphere and plasmasphere, we would have a very different atmosphere, making it impossible for life to exist.
Answers
Answer:
When solar material streams strike Earth’s magnetosphere, they can become trapped and held in two donut-shaped belts around the planet called the Van Allen Belts. The belts restrain the particles from traveling along Earth’s magnetic field lines, continually bouncing back and forth from pole to pole.

How are some humans using more than their fair share of water? What is the effect of using water on environmental systems?
Please write a full paragraph and cite evidence.
Answers
Answer:
Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

Why is pollen needed in plant reproduction?
fertilization takes place in the pollen
pollen contains the egg cell
pollen contains the sperm cell
egg cells stick to pollen
Answers
Answer:
The pollen contains the sperm cell.
Explanation:
When the pollen grain lands on the stigma and begins to grow a tube, the pollen tube grows down the style to the ovary. Each pollen grain contains a male reproductive cell known as the sperm cell. The sperm cell will go down the tube and unite with an egg cell in the ovary. When the egg cell and the sperm cell unite, fertilization occurs. This newly fertilized egg will make many new cells and will grow into a tiny plant embryo. The embryo is located in the ovule. The ovule is located inside the ovary. The ovule grows into a seed. The plant embryo usually remains in the seed until it is planted in the soil. The stigma, style, ovule, and ovary all make up the female part of the flower called the pistil.

This is an illustration of a typical food web. You might see a food web like this where you live. The organisms responsible for changing sunlight into food would be the Response area. Grass is one of these. You can see that the grasshopper and rabbit eat the grass and the bird and the shrew eat the grasshopper. Imagine that there was a big increase in the number of snakes in this area. We would then expect the Response area numbers to drop. In this food web, we consider the hawk a Response area. If the hawk population increases, we would see a drop in birds and shrews and snakes! The fungi and bacteria in the food web are examples of Response area. They break down any and all dead organisms.

Coral reefs are home to a quarter of all marine species on Earth. What is one
consequence of decreased biodiversity in coral reefs?
A. More niche opportunities for land species
B. Increased number of predatory species
C. Increased stability of all other biomes
D. Less seafood in the human food supply
Answers
Answer:
D
Explanation:
A is wrong, it's talking about land. B is an increase in biodiversity. C is wrong because other biomes depend on reefs
The one consequence of decreased biodiversity in coral reefs can be increased number of predatory species. The correct option is B.
What are predatory species?Predatory animals are those that kill and then eat other animals, or "prey on" them. Predatory animals include hawks, lions, alligators, and humans. When one party victimizes another for personal gain, the term predator is also used.
Predation is a natural feeding behavior of animals, plants, and microorganisms in which one species feeds on another for survival. Predation is the process by which one animal kills another and consumes it as food.
Increased predatory species may be one of the consequences of decreased biodiversity in coral reefs.
Fish, marine worms, barnacles, crabs, snails, and sea stars are all predators of coral polyps' soft inner tissues. In extreme cases, large predator populations can devastate entire reefs.
Thus, the correct option is B.

3. Walking -
4. Feeding the stray animals -
5. Using back page of paper -
6. Using fan -
7. Watering the plants -
8. Sweeping -
Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?
Answers
Answer:
Explanation:
1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.
2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption
3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.
Answer:
Explanation:
1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.
2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.
3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.
4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while
Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,
Thus fan helps to reduce greenhouse gas emissions.
5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.
