Question

given the following aquatic food web, identify what would happen to the blue whales and phytoplankton populations if the krill were extinct. please be detailed, specific, and write in complete sentences.

Explanation:

Krill are a primary food source for blue whales. Without krill, blue whales would lack food, leading to a decline in their population due to starvation or migration in search of food. Phytoplankton are consumed by krill. With krill extinct, phytoplankton would face less predation pressure, so their population would likely increase as they have fewer consumers.

Answer:

Blue whale population would decline due to lack of food. Phytoplankton population would likely increase due to reduced predation by krill.
