Consumption efficiency 

Consumption efficiency is the proportion of production at one trophic level (Prod n -1) that is eaten by, or ingested, by the next trophic level (In)

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%.

Consumption efficiencies for carnivores are typically higher than those of herbivores and vary from 5–100% Vertebrate predators commonly consume more than 50% of their prey.

Consumption efficiency of terrestrial herbivore range between 0-15 %, means 85 – 100% NET terrestrial plant goes into decomposer chain.

Carnivore assimilation efficiencies are often about 80%, because carnivores consume largely soft tissue,  Assimilation efficiencies for herbivores average only about 5–20% 

Assimilation efficiencies of aquatic herbivores have higher  than terrestrial herbivores.
