Question
The Biomass available for consumption by the herbivores and decomposers is called
Options
A.net primary productivity
B.secondry productivity
C.standing crop
D.gross primary productivity
Solution
Net Primary Productivity (NPP) is the weight of organic matter stored by producers in a unit area/volume per unit time. NPP is is equal to the rate of organic matter created by photosynthesis minus are rate of respiration and other loses. Stored biomass is transferred from one trophic level to anothe trophic level.
Secondry Productivity is the rate of energy storage at consumers levels-herbivores, carnivorous and decomposers.
Gross Primary Productivity (GPP) is referred as a total rate of photosynthesis including the organic matter used up in repiration during the measurement period.
