Since the word hypothesis means an educated guess, I'd go with "Salmon are more prone to infections during the summer than in other seasons" because the others are just stating what it seems to be, facts.

Sustainable use of the environment

Explanation:

Be it the ecosystem or the food you eat, if you just take up whatever you need instead of over exploiting the resources, another life can benefit from it. The relationship we need to form with our environment should be mutualism or commensalism but not parasitism.

1. Increased efforts to conserve areas such as rain forests are necessary in order to
Nataliya [291]

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.
