The difference between gross primary productivity and net primary productiviry is determined by the respiration of primary producers.
a. true
b. false

True

Explanation:

Gross primary productivity (GPP) of a system is defined as the rate by which the primary producers trap the solar radiation during the process of photosynthesis. The gross primary productivity is represented as total photosynthesis per unit area in a given time.

The net primary productivity (NPP) refers to the energy available to the plants for their growth after cellular respiration and is represented as plant growth per unit area in a given time.

Plants use part of the gross primary productivity in cellular respiration to produce the energy required to perform other vital functions. Hence, the energy consumed in cellular respiration differentiates the gross primary productivity and the net primary productivity.

NPP = GPP - Plant respiration

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

hope this !

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
