Plants and algae
What is the primary role of producers in an ecosystem?
Transform solar energy into food
How do autotrophs convert sunlight into chemical energy?
Through the process of photosynthesis
What happens to the small amount of stored chemical energy when autotrophs are consumed by heterotrophs?

Why do higher level heterotrophs get very little glucose from the organisms they consume?
Glucose is broken down before reaching higher level heterotrophs
