Energy Pyramids & Food Webs

​By the end of class, I can independently explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide, and oxygen).

In your own words, what is the goal of this lesson?

In case you don't remember...

​By the end of class, I can independently explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide, and oxygen).

Open Ended

Since the energy cannot just stop at the top of the energy pyramid, what do you think happens to it?

Open Ended

Since a pyramid shows that energy stops at the top (and we know that energy doesn't just stop), what other models show that energy is reused?

Open Ended

Where do you think the lost energy goes between energy levels?

Open Ended

You just learned that biomass is the energy in living organisms. You also learned learned that biomass decreases as the trophic levels increase. Where do you think that the lost energy goes?

Multiple Choice

Where does all energy start from?

• Producers

• Apex Predators

• Chemical Reactions

• The Sun
