An ecosystem experiences a rapid increase in the algae population as a result of lawn fertilizer entering the system through storm drains. The food chain below is part of the ecosystem.

The mentioned question is not complete. The complete question is:

An ecosystem experiences a rapid increase in the algae population as a result of lawn fertilizer entering the system through storm drains. The food chain below is part of the ecosystem. AlgaeMinnowsSalmonBear As the algae population begins to grow, what will happen to the minnow population? A. It will soon start to grow. B. It will be unaffected by the change. C. It will first decline, then grow. D. It will soon start to decline.

The correct answer is option A.

Explanation:

A linear demonstration of the flow of energy in an ecosystem is termed as the food chain. The process begins with the producers and terminates with decomposers. However, a food chain can get affected in broader terms if there is any kind of change witnessed in the population of the species coming within a specific food chain.  

Like in the given case, with the increase in the population of algae, there will be an upsurge in the population of minnows because, with the increase in algae, the minnows will be able to get more food to consume and thus, their population also rises.  

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)

a physical change is being made.
