Which one of the following ecosystems has the highest annual net primary productivity?
1 Desert
2 Tropical deciduous forest
3 Tropical rain forest
4 Temperature evergreen forest
Explanation:
Net primary productivity (NPP) is the biomass that is available for consumers (herbivore and decomposers) for consumption. Since in the tropics where rain forests are found, water, light, and high temperatures are readily available, and there is a dense concentration of green plants at all levels from the lower stories to the canopy, it is no wonder that these forests have very high levels of productivity.

How much of the net primary productivity of a terrestrial ecosystem is eaten and digested by herbivores?
1 \(1 \%\)
2 \(10 \%\)
3 \(40 \%\)
4 \(90 \%\)
Explanation:
Each trophic level in the grazing food chain transfer 10 percent of energy to the next trophic level (10% law).

The rate of formation of new organic matter by deer in a forest ecosystem is called:
1 Primary productivity
2 Secondary productivity
3 Standing crop
4 Net Primary productivity
Explanation:
The rate of production of organic compounds by the heterotrophs is known as secondary productivity.

In the equation \(\mathrm{GPP}-\mathrm{R}=\mathrm{NPP}, \mathrm{R}\) represents:
1 Radiant energy
2 Retardation factor
3 Environment factor
4 Respiration losses
Explanation:
Gross Primary Production, GPP, is the total amount of \(\mathrm{CO}_{2}\) that is fixed by the plant in photosynthesis. Respiration, \(\mathrm{R}\), is the amount of \(\mathrm{CO}_{2}\) that is lost from an organism or system from metabolic activity. ... Therefore, NPP = GPP - R . This is the available biomass for herbivores.
