Answer:
1. Protect biodiversity
2. An indicator species
3. Biomagnification
4. Cutting down all the trees for lumber
5. Bioaccumulation
Explanation:
1. Conserving areas such as rain forests protect biodiversity because rain forests hold one of the highest biodiversity. They carry different types of resources that support different forms of life and at the same time, the organisms that live there support each other as well.
2. An indicator species is an organism that scientists can observe to see if there are changes in the environment it lives in. They judge the change or the implications based on the absence of the species in the environment (in which they used to be present), the presence of the species, and markers of adaptation due to the change in the ecosystem.
3. Biomagnification is a term used when contaminants that were consumed by the organisms in the lower trophic level are passed on to the next trophic level in higher concentrations. This is why those in the highest trophic levels are affected the most because they get the higher concentration of contaminants. DDT was banned when this phenomena was observed.
4. The greatest decrease in rain forest stability would be due to the cutting of trees. We can disrupt stability by gathering resources like nuts from some trees or when you remove one species of plant for medicine. However, the trees are an essential part of the rain forest because each part or area of the tree support different organisms. By cutting the whole trees off and several of them, you doom the organisms that rely on them as well.
5. As mentioned above, bioaccumulation is often interchanged with biomagnification but they differ in the usage of the terms. Like biomagnification, it talks about the accumulation of contaminants in organisms that ingest or absorb them. But bioaccumulation is a term used in a smaller scale, where it talks about the accumulation of the contimants in the tissues of the organism and not how they are passed on.
My guess would be D.. Not for sure tho.
Since people with HIV have weakened immune systems it would be:
C) People with HIV are unable to fight off these rare diseases.
<span>The question is asking how over-irrigation is damaging to soil. Over-irrigation means that too much water is being delivered to the soil, and too much water can wash some other important ingredients out - such as organic material. Therefore, the correct answer is:
a. It reduces the amount of organic material in soil.</span>
