In communities the food chain begins with plants, which are the producers. Animals eat these producers or some other animal. A food chain is the transfer of food energy from the plants through a series of animals with repeated eating and being eaten behaviors. All living things make food chains. Plants need the sun to grow.
Many insects eat plants, many toads eat insects, many snakes eat toads, and many hawks eat snakes.
This is another example of a food chain. Whenever we eat food, we are members of a food chain. Label tags with grasshopper, snake, or hawk. Instruct students to have science journals on hand. Copy or make an overhead transparency of the information sheets.
