Autotrophs → Organisms that rely on other organisms for their energy and food supply
Aerobic respiration → The use of inorganic molecules other than oxygen to accept electrons at the "downhill" end of electron transport chains.
Gross Primary Productivity (GPP) → Rate at which all the plants in an ecosystem produce net useful chemical energy; equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy (gross primary productivity) and the rate at which they use some of that energy through cellular respiration. Compare gross primary productivity.
