I used this activity on the SmartBoard as a review for my students. It incorporates producers, consumers, and decomposers. It also includes the three types of consumers: herbivores, carnivores, and omnivores. Linked to the powerpoint are different activities for the students to complete. These activities can be printed, manipulated on the SmartBoard, or discussed as a whole group. I also allowed my students to utilize their white board slates to complete the food chains individually during the whole group instruction.
