2 producers: seagrass bacteria
1 tertiary consumer: small sharks
2 primary consumers: crustaceans ,small fish
1)The organisms that carry out photosynthesis would be the producers. They produce food and oxygen for secondary and tertiary consumers.
producers: bacteria, algae,phytoplankton , etc
primary consumers: , small fish, crustaceans ,etc
2)There are many organisms that carry out photosynthesis in the ocean. For example phytoplankton which are tiny single celled plants that float in the water. They use sunlight, carbon dioxide and nutrients to produce food.
tertiary consumers: whales,sharks,seals , sea lions, etc
secondary consumers:,jelly fish, big fish stingrays coral, etc
3) Energy flows between different trophic levels in a food chain or food web like shown above. When one of the organisms eats the other it gains energy from that organism and so on. So energy flows from the producers to the primary consumers then secondary consumers and (in this food web) finally the tertiary consumers.
