I agree with the other persons answer

Answer 2

Step-by-step explanation:

By fishing the prawns and small fish to near extinction, the bacterial population will increase and so will the mold, because the prawns and small fish that make use of these sources of nutrition are no longer available.

The heron and pelican population will reduce because these birds depend on the prawns and small fish for nutrition, hence, the herons and pelicans will try to look for another source of food, and the will therefore migrate to somewhere they can get food.
