Food Chains Information

Transcription

1 Food Chains Information All living things depend on each other to survive. A food chain shows the relationshipss between the plants and animals that depend on each other. A food chain shows how the sun's energy is transferred first to plants, and then to animals in the community. In a food chain there are Producers and. Producers: Plants are called producers. They are able to use light from the Sun to produce their own food. Even though they are always at the bottom of the food chain, plants are very important to the life of all other life forms. : Animals are unable to make their own food. In order to survive, animals have to eat plants or other animals for food. Animals are called consumers. There are many levels of consumers. As the level becomes higher, there are fewer consumers. Types of : Herbivores: Animals that only eat plants. Carnivores: Animals that only eat other animals. Omnivores: Animals that eat both plants and animals. As the energy from the Sun is passed from the lower level producers to the higher level consumers, the amount of energy available becomes less and less. Another way to view a food chain is in a pyramid. A pyramid helps us to understandd that there must be more life forms in the lower levels and fewer on the higher levels in order to maintain this delicate balance in the community.

You can leave the labels attached to the animal cards, or you can cut them off and keep them for matching together with the picture cards. 3. Divide the cards in to groups: food chains with 3 links, food chains with 4 links, food chains with 5 links. Be sure to store the correct control chart with the correct group of cards. 4. Using the Food Chain Information page, explain to the children the process of the food chain starting with the sun. 5. Use the food chain diagrams to discuss the Producers and various. 6. Demonstrate a food chain using the cards and arrows. Show the child how to check their work using the correct control chart. 7.Once the children understand the concept of food chains and the food chain pyramid, they can use the black-line master to illustrate their own food chain pyramid. To make a set of 3-part cards: print 2 sets of the animal cards and cut the labels off 1 set. The children can read the labels, match them to the correct picture cards
