    Food chain

    Definition: a series of organisms each dependent on the next as a source of food.

    Create 4 food chains using NZ wetlands plants and animals . Use the food chain above as an example.

    Definition: A food web is similar to a food chain but larger. A food web uses arrows to show the energy relationships among organisms. Food webs show how plants and animals are connected in many ways.
