Question

An ecologist was studying a tightly coupled trophic cascade off the coast of Antarctica. The trophic cascade has four levels: leopard seals feed on Adele penguins, which feed on krill, which feed on phytoplankton. She recorded an increase in the abundance of leopard seals and made a prediction for other organisms. Which of the following predictions would be incorrect (choose ALL options that are incorrect)? an increase in the krill population. an increase in the number of penguins. an increase in the abundance of phytoplankton. a decline in the abundance of phytoplankton. a decline in the number of penguins.

Answer 1

If population of leopard seals increase ,they will eat more Adele penguin so less predators left for krill so their population will also increases and so less population of phytoplankton remain

So 1st and 4rth one is correct answer.
