What is alive in your ecosystem?
Lesson 1 – Activity 3 Worksheet
Using the list of Wyoming organisms that we just made on the board, write the
organisms under the correct topic heading of either a producer, consumer, predator, or
decomposer. Some of the organisms may fit under more than one heading.
Producers
Consumers
Predators
Decomposers
Now that you have made your list on the other side of the page, use some of the
example and create your own trophic cascade by filling in the diagram below. Make
sure you label each shape as a producer, consumer, predator, or decomposer. Write
the organisms’ names inside the shape.
