Food Chain Practice Sheet

Food Chain Lesson

What is a food chain ? A food chain explain how living thing in order to stay alive.

Food Chain Lesson. What is a Food Chain?

All living things are linked to each other. They need other living thing to survive. A food chain is like a ladder. Imagine you are standing in the middle if a ladder. You would eat animals plants that are below you on the ladder . The animals above you on the ladder would eat you.

Food Chain Lesson. What is a Producer?

The sun is needed in a food chain. It gives plants and animals energy. There would no be a food chain at all without sunlight. All food chain begin with a link called producer . Producer makes food from nonliving things. A green plant is an example of a producer. Have you ever wanted a plant? If so you have helped a plant makes it food. The plant takes that water and uses the sun's energy to combine it with carbon dioxide. This is how the plant make it is own food. This gives the plant nourishment. It is like when you eat healthy meal.

Food Chain Lesson. What is Consumer, Herbivore , Carnivore , and Omnivore

The next link is called a consumer. A consumer is any living thing that needs a producer for food . There are many types of consumer. One type of herbivore . This is an animal that only eats plants. A plant gets nutrient from the food it makes. A plant gets nutrient from food it makes. Then an animal gets nourishment by eating the plant. The second type of consumer is called carnivore. Animals that only eat other animals are called carnivore. Animals that only eat other animals are called carnivore. The third type on consumer is called an omnivore. Animals and people who eat both plant are called omnivore. What of consumer are you ?

Food Chain Lesson. What is a Decomposer ?

The last link in a food chain is called decomposer. Decomposer like bacteria and fungi are living thing that eat dead plant and animal or help them decay. Decomposer are nature garbage collectors. They help to keep the earth clean and healthy. Can you imagine what Earth would look like if each plant and animal died just laid on the ground forever? It would be a very crowed and stinky world. You can see that even thought most decomposers are small they do have very big job.

Food Chain Lesson. Finished

Let's look at a food chain in a action in the sea. At the the bottom of the Food Chain there are plants and plankton Fish and animal like shrimp jellyfish and sea stars need to eat plankton to live. Then larger fish like tuna and mackerel eat jelly fish and shrimp. Then even larger fish and animals such as sharks seals and people eat them. Do you know what would happen if all of the plankton disappeared ? The shrimp and jellyfish would die because they would not have any food so the tuna and mackerel would not have as much to eat and they could start die. If this went up the Food Chain . It would affect our lives as well just like each type on a ladder is important to make it to the top we need each type part of the food chain to keep the balance of life the same . This way all living thing can survive.
