Ocean animals are linked by food chains that make all ocean creatures dependent upon each other. The marine food chain is similar to a pyramid. The few largest creatures at the top could not exist without the layers of increasingly smaller animals below it. Tiny animals eat microscopic plant life and use the nutrients for their own growth.
Marine food webs. Feeding relationships are often shown as simple food chains – in reality, these relationships are much more complex, and the term ‘food web’ more accurately shows the links between producers, consumers and decomposers. A food web diagram illustrates ‘what eats what’ in a particular habitat.
19 Οκτ 2023 · Marine Food Pyramid. This food pyramid displays a basic marine food web. Organisms on the first trophic level, such as plants and algae, are consumed by organisms on the second trophic level, such as conchs and blue tangs.
