Individual Organism Metabolism

Metabolism is the balance between energy and materials flow.

energy uptake, use and loss

nutrient uptake as food

excretion

Processes and efficiencies

ingestion - amount eaten

assimilation - amount digested

production - amount converted into new growth or storage

 

assimilation efficiency = assimilation/ingestion

gross production efficiency = production/ingestion

net production efficiency = production/assimilation
