Summary Plants and animals interact. Plants are producers. Animals are consumers. Decomposers get food by breaking down wastes or dead

things. Living things get their energy from food. Animals cannot make their own food, so they eat other living

things. A food chain is the flow of food in an ecosystem from one

living thing to another. An energy pyramid show that the amount of usable energy in

an ecosystem is less for each higher animal in the food chain.
