What is the difference between gross and net primary productivity

As long as the rate of biomass production surpasses that of what is needed for cellular respiration, plants will grow and propagate. Several factors can affect GPP and NPP such as climate, type of soil, and the availability of water and nutrients in the area where they are grown.

At present, the human burden on the ecosystem has raised questions of how it can sustain life in the future. The biomass generated is used for the cellular respiration of plants which it converts into nutrients and ATP necessary for cell production. The ideal setup is that biomass production should always be higher than what is needed for cellular respiration so that plants will grow. Difference Between Gross and Net Productivity.

Other factors that can lead to a decrease in Primary production can be water. A decrease in any of these factors can cause a decrease in the level of Primary Production.

The process of primary production must take place as it is the base or foundation of the food chain. Therefore if due to any reason it gets disturbed, the entire food chain will be shaken. Both of them are different in terms of dependency on chlorophyll and terms of consumer and producer. NPP stands for net primary production. It is defined as the rate at which every autotroph which is included in the ecosystem produces net chemical energy.

It is the difference between the rate of total useful chemical energy produced and the rate at which some of its useful chemical energy is used for the respiration process. GPP stands for Gross primary production.

It refers to the total productivity including the energy utilized for respiration by the producers 3. It depends on chlorophyll content 4. It is the amount of organic matter stored by producers per unit area in unit time 2. It refers to the net productivity that is converted to organic matter excluding the energy utilized for respiration R by the producers 3.
