Create a food web with the following organisms:

grass, Sun, rabbits, insects, deer, hawks, shrubs, snakes, foxes

- Use arrows to demonstrate the flow of energy.

- Label each level.

20

Create a simple food chain of an organism that you have researched. Be sure to label the

flow of energy using arrows. Your food chain must include the following labels: primary

producer, primary consumer, secondary consumer, and tertiary consumer. You may add the

following terms to your food chain: herbivore, carnivore, and omnivore.

21

Cut out and arrange the pictures into a food web. Add arrows to indicate the flow of energy

throughout the food web. Once correctly placed, glue down the pictures. Label the

organisms on your food web as follows: Prey, Predator, Producer, Primary Consumer,

Autotroph, Heterotroph, Decomposer, Secondary Consumer, Carnivore, Omnivore, Herbivore,

and Tertiary Consumer. An organism may have more than one term, and terms may be used

multiple times or not at all.
