Back

The Owl receives the least amount of energy from the producer.

Back

Secondary consumers are organisms that eat primary consumers (herbivores). Examples include Weasels, Red Foxes, and Frogs.

Front

What is the role of decomposers in an ecosystem?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can support sustainably.
