In order to calculate NPP in units of grams Carbon, she must first convert her found value using a conversion formula (given below). In addition, in order to calculate GPP she also requires the Lake’s respiration (R) to have been determined. True or false?

Hi, the question is incomplete. However, it is about the calculation of NPP and GPP.

NPP is known as Net Primary Productivity while GPP is known as Gross Primary Production. NPP is the total amount of carbon consumed during the process of photosynthesis. It is equivalent to the difference between GPP and the amount of carbon used up during respiration (R). GPP is the production rate of the material.

Explanation:

NPP is known as Net Primary Productivity while GPP is known as Gross Primary Production. NPP is the total amount of carbon consumed during the process of photosynthesis. It is equivalent to the difference between GPP and the amount of carbon used up during respiration (R). GPP is the production rate of the material.

NPP = GPP - R

i dont know the answe

the answer is c.the valence of the atoms combine .
