#Unit 10. Ecological Principles

Trophic-level transfer efficiency is low for the two reasons

a- Many organisms cannot digest all their prey.  

b- Much of the energy assimilated by animals is used in maintenance.

c- The dead organisms and feces become dinner for decomposers.

Consumption efficiencies  Forests range from 1–2%.  In grasslands, most plants are non woody range from 30–60%.  In aquatic ecosystems (most plant and algal biomass can be consumed by herbivores) range from  60–99%.
