Question

which of the following is the most likely flow of energy in an aquatic ecosystem? a. phytoplankton → mammal → zooplankton → fish b. phytoplankton → zooplankton → fish → mammal c. zooplankton → phytoplankton → mammal → fish d. mammal → fish → zooplankton → phytoplankton please select the best answer from the choices provided a b c d

Explanation:

In an aquatic ecosystem, energy flow starts with primary producers like phytoplankton that perform photosynthesis. Zooplankton feed on phytoplankton. Small fish eat zooplankton, and larger mammals may eat the fish. Option b follows this correct sequence of energy - transfer from primary producer (phytoplankton) to primary consumer (zooplankton), then to secondary consumer (fish) and finally to a tertiary consumer (mammal).

Answer:

B. phytoplankton → zooplankton → fish → mammal
