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

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

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

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

6. Food Chains & Food Webs Food chains and webs show how 
energy moves in an ecosystem. Food 
gives the energy to the organisms in 
an ecosystem. 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. First paragraph pg. 144

7. 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

9. TextQuest Answer questions in your Science Journal. 1. Where is the greatest amount of energy in an Energy 
Pyramid? Why? 2. How do herbivores and carnivores get their energy? 3. What niche (role) do decomposers play in an 
ecosystem? 4. What do decomposers make when they break down 
remains of dead organisms? Don't forget to write your
