2. In polar regions, phytoplankton.
natka813 [3]

Answer:

b. thrive during the summer, when sunlight increases

Explanation:

Phytoplankton production is highly associated with latitude and season. In polar regions, phytoplankton production is reduced to the summer (and eventually spring) season. In consequence, the zooplankton that eats phytoplankton only can survive during the spring and summer seasons. On the other hand, in tropical areas, there exists a nearly constant phytoplankton production all year round.
