Why can't carnivores consume all prey biomass?
Cannot eat bones, hooves, and claws
How does respiration cause biomass loss?
How does respiration cause biomass loss?
Glucose used for energy release, not biomass
What is urea?
What is urea?

Why fewer organisms at higher trophic levels?
Why fewer organisms at higher trophic levels?
Only small % of biomass transferred to each level

What does respiration produce instead of biomass?
Carbon dioxide as a waste product
