Lesson Objective

Describe the metabolic and behavioral strategies organisms use to acquire and use energy.

Calculate and explain how changes in energy availability propagate through trophic levels, affecting population sizes and ecosystem biomass.

What metabolic strategies do autotrophs and heterotrophs use to capture and utilize free energy?

How do changes in primary productivity impact the carrying capacity and structural design of food webs?
