A certain species of fish (A) preys on a smaller species of fish (B). The smaller species of fish mostly consumes seaweed. What would be the effect of overfishing species A? If species A is overfished, then the drop in population of species A will have a(n) (direct, indirect or cascading) effect on the population of species B. The population of species B will increase. A(n) (direct, indirect, or cascading) effect of overfishing would be a drop in seaweed, because the larger population of species B would consume more seaweed.

B. The population of species B will increase, A(n) (direct, indirect, or cascading) effect of overfishing would be a drop in seaweed, because the larger population of species B would consume more seaweed.

Explanation:

As population of Fish A is directly dependent on population of fish B and population of fish B is dependent on seaweed. Overfishing of species A will have a direct effect on species B and population of species B will increase as there will be less predator (species A).

Due to overfishing of species A resulting into increase in species B, there will be an indirect drop in the seaweed, because the larger population of species B would consume more seaweed.

Hence, the correct answer is "B".
