- What is primary productivity? Why does it vary in different types of ecosystems?
- State the relation between gross and net primary productivity.
- Primary productivity : Production of biomass/produced energy per unit area in a certain time period by plants during photosynthesis.It depends upon - plant species inhabitating a particular area, environmental factors availability of nutients, photosynthetic capacity of plant.
- GPP - R = NPP
NPP = Net Primary Productivity
GPP = Gross Primary Productivity
R = Respiration Losses
