1Examples of producers include carnivores and herbivores. Yes No Do you agree with the statement?

2Omnivores eat plants and animals. Yes No Do you agree with the statement?

3Consumers have the greatest amount of energy in an ecosystem. Yes No Do you agree with the statement?

4The organisms at the top of the energy pyramid have the least amount of energy. Yes No Do you agree with the statement?

Food Chains & Food Webs Producers make their own food by using energy from the sun, like plants. Consumers eat other organisms to get energy, all animals are consumers. 1. Herbivore is an animal that eats only plants. 2. Carnivore is an animal that eats only other animals. 3. Omnivore is an animal that eats both plants and animals. Decomposers are organisms that eat waste or dead organisms and make nitrogen compounds that can be used by plants. The arrows in a food chain show how energy moves from the food to the animal. Food webs contain many food chains that show many relationships between organisms. Food chains and webs show how energy moves in an ecosystem. Food gives the energy to the organisms in an ecosystem. First paragraph pg. 144

Energy Pyramids An energy pyramid is a diagram that shows the amounts of energy that flow through each level of a food chain. The most energy is at the bottom of the energy pyramid because some of the energy is used up before the organism gets eaten. Activities like running, breathing and thinking turned the food into the energy of body heat. Energy does not disappear, it just changes form. First paragraph pg. 146 Food Chains
