b. Classify populations of organisms as producers, consumers, decomposers by the role they serve in the ecosystem.
c. Differentiate between three types of consumers (herbivore, carnivore, omnivore)
d. Categorize organisms as predator or prey in a given ecosystem.
e. Sequence the flow of energy through a food chain beginning with the sun.
f. Predict the possible effects of removing an organism from a food chain.
