Answer:
B. Humans will have less salmon available to eat.
Explanation:
First off, you always want to be wary of choices that are kinda extreme. Take for example, choice A., which says All of the oxygen in the atmosphere will disappear. The problem doesn't say that the plankton population will go extinct, just decrease, so oxygen from the atmosphere won't completely disappear. There are also other sources of oxygen. Moving on, C. says that the shrimp will completely disappear from the sea. This is wrong because once again, plankton won't go extinct in the problem. The shrimp population will decrease but not go extinct. Next, D. Choice D is baloney because a decrease in plankton means less food for salmon, which means the salmon would die in the area. That leaves Choice B. Choice B. makes sense because of something called the bottom-up model, which states that an increase or decrease in the amount of organisms in a lower trophic level will affect the organisms in the above trophic levels. We can see that in action here; if the amount of plankton drop, the amount of shrimp salmon will drop, which means less salmon for humans.

The human activities in addition to natural factors that can alter the terrestrial ecosystem is deforestation.
<h3>The effects of deforestation on food web</h3>
Deforestation is a the clearing of trees in a large area of land which can be purposeful or by nature.
Human activities that leads to clearing of trees include the following:
- dam construction and infrastructure development.
One of the negative effects of deforestation on food web is the reduction in food availablity. This is so because of the loss of biodiversity that are source of food to man.

Deforestation affects entire ecosystems, including the organisms that live in them.
In <em>rainforests</em>, deforestation has devastating effects. Wildlife diversity, for instance, tends to decrease as species are displaced from their natural habitats. Animals go to new places in search of shelter and food. In many cases, they die of hunger or are threatened with extinction due to the spread of diseases.
Deforestation also affects rivers, different streams of water and the soil. The soil, which provides essential nutrients for vegetation, is exposed to more sunlight and heavy rainfalls that erode it. Erosion makes the soil drier and infertile.
