Question

the net primary production of a pine forest on a lava flow on mount fuji is about 175,000 kcal/m2/yr, and the plant respiration is estimated to be 115,000 kcal/m2/yr . what is the total amount of energy transferred during photosynthesis for this ecosystem?

Answer 1

For this environment, 290,000 kcal/m2/yr of energy is transmitted during photosynthesis.

The amount of energy held by an ecosystem's biomass after energy is lost to metabolism and maintenance is taken into account and is referred to as the ecosystem's net primary productivity. The difference between net primary productivity and gross primary productivity is that the latter refers to the entire energy input into the ecosystem before accounting for energy loss.

In order to respond to this issue, we must understand that gross primary productivity (GPP) is the amount of energy that is gathered during photosynthesis and turned into chemical energy, and net primary productivity (NPP) is the difference between GPP and respiration rate.

Therefore, we must add NPP to the respiration rate in order to calculate GPP. If NPP = 175,000 kcal/m2/year, then this

R is 115,000 kcal/m2/year.

NPP equals GPP - respiration

GPP = NPP + R after that.

GPP = 155,000 + 175,000 kcal/m2/yr

GPP = 290,000 kcal/m2/year
