Growth is controlled by limiting factors.
Gross Primary Productivity
The rate at which an ecosystem produces biomass.
Net Primary Productivity
The total productivity after plant respiration (GPP-respiration= NPP)
Law of Tolerance
The success of a species depends on the extent of which its optimum environmental conditions are satisfied.
