How to: Use food webs in education

View all subject updates

When teaching food chains and food webs, it will be useful to understand some of the key words used to explain feeding relationships and the transfer of energy in the ocean:

Consumer

A living thing that relies on feeding on other living things for its energy, e.g. a shark is a consumer because it eats fish or a sea urchin is a consumer because it eats algae.

Photosynthesis

The process by which producers create sugar (and therefore energy) from carbon dioxide and water using sunlight.

Predator

An animal that eats other animals, e.g. a manta ray is a copepod predator.

Prey

An animal that is eaten by another animal, e.g. a crown-of-thorns starfish is the prey of the Triton’s Trumpet.

Producer

A living thing that produces energy via photosynthesis, e.g. algae is a producer because it creates energy from sunlight, carbon dioxide and water rather than eating something else.
