A food web consists of many food chains.
A food chain only follows just one path as animals find food.
eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass.
A food web shows the many different paths plants and animals are connected.
eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal. The snake may eat a beetle, a caterpillar, or some other animal. And so on for all the other animals in the food chain.
A food web is several food chains connected together.
Producer - usually a green plant that produces its own food by photosynthesis
Decomposer - an organism such as bacteria and fungi that breaks down dead organisms and their wastes. . (They do not 'eat' the food like scavengers, as they have no mouth-parts. Instead they break down solid matter into liquids which they can absorb.) Examples: bacteria and some fungi.
Primary Consumer - Animals that consume only plant matter. They are herbivores - eg rabbits, caterpillars, cows, sheep, and deer.
Secondary Consumer - Animals that eat primary consumers (herbivores).
Tertiary Consumer - Animals that eat secondary consumers ie carnivores that feed on other carnivores.
