A predatory sea slug eats hydrozoans that have just eaten plankton. What advantage does this give the sea slug?
It reduces competition for food.
It allows the sea slug to obtain more energy in one meal.
It helps the sea slug digest food faster.
It increases the number of hydrozoans.

If kleptopredation becomes common in an ecosystem, what might be a likely effect on the prey population (such as hydrozoans)?
Prey population will increase rapidly.
Prey population will remain unchanged.
Prey population may decrease due to increased predation pressure.
Prey population will never be affected.

How does kleptopredation alter the movement of energy in a food web compared to standard predator-prey interactions?
It reduces energy transfer in the ecosystem.
It adds extra steps that waste energy.
It allows direct transfer of energy from the prey's prey to the predator, making energy transfer more efficient.
It prevents energy from being recycled.
Answer explanation
It allows direct transfer of energy from the prey's prey to the predator, making energy transfer more efficient.
