1. Question! 10/28 What are some ways that organisms in the forest interact BESIDES eating each other (predator-prey)? Halloween Party! Tractor Driving!

2. Review! Make up a food chain using some of the organisms to the left.

3. Review! Now incorporate all of them into a food web!

4. Review! Finish by labeling the primary producers, primary consumers, secondary consumers, etc! THEN LABEL the herbivores, carnivores, etc.
