Question 36 • EF Environmental Science 1st Nine Weeks
Answer:
phytoplankton, zooplankton, fish, mammal Phytoplankton are producers, so they produce their own food by using energy from the sun. All other organisms in a food chain obtain energy from other organisms, either producers or other consumers. Zooplankton feed on phytoplankton, so they would obtain their energy from the phytoplankton. Some small fish species feed directly on zooplankton, obtaining their energy from the zooplankton. Some species of aquatic mammals feed on those fish species.
