Answer:
The correct option is A. It will soon start to grow.
Step-by-step explanation:
In biological terms, a food chain can be described as a linear representation of energy flow in an ecosystem. It usually starts with the producers and then represents a chain until the decomposers.
A change in any of the species population of the food chain can affect the food chain widely. For example, in the question above, as the population of algae increases, the population of minnows will also increase. This is because there will be more supply of food for the minnows.
