'A food chain is a single path, which help us to work out who eats whom in a habitat, in order to get the energy and materials required for nutrition. Typically food chains involve around four steps. It is unusual for them to be longer because energy is lost between each step and so the energy available for the next organism decreases. Altering one link in a food web has big consequences for the whole system. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.
