Question

Which organisms will experience a population increase due to a new fatal disease affecting squids?

A Shrimp and krill

B Orca and sea turtles

C Reef sharks and sea turtles

D Reef sharks and tuna

Answer 1

The answer is A Shrimp and krill

If a new fatal disease affects squids, their population would decrease. As squids are a prey species for many different predators, a decrease in the squid population would likely lead to an increase in the population of their predators' prey. Shrimp and krill are common prey items for squids, so a decrease in the squid population would lead to a decrease in the predation pressure on shrimp and krill. This, in turn, would likely cause an increase in the population of shrimp and krill.
