In this powerpoint producers, consumers, detritus, carrion, scavengers, detritivores, decomposers and the food chain arrow are presented with examples of each. The powerpoint is a great way to begin the unit or to reteach the concepts.

There is also a matching differentiated foldable that goes along with the powerpoint, you can purchase them as a bundle with a discount:
