ANSWER

The main difference between gross primary productivity and net primary productivity is, gross primary productivity is the complete amount of food generated and net primary productivity is the difference between GPP and the quantity of food used by producers for respiration.

How does gross primary productivity differ from net ?

Gross primary production is the amount producers create over a set period of time whereas net primary productivity is former once respiration has been accounted for.

How do gross primary productivity and net primary ? Gross Primary Productivity (GPP) is all the biomass (think glucose for simplicity) that autotrophic organisms make through photosynthesis in a given period of time. Net Primary Productivity (NPP) is GPP minus all autotrophic respiration (that conv

What is Net Primary Productivity? Net Primary Productivity or NPP can be defined as the rate of accumulation of biomass or energy. The energy utilised during metabolic processes such as respiration is excluded from gross productivity (GPP). NPP is calculated primarily by an increase in the biomass in a unit time per unit area.

What is the difference between gross and net primary ? Gross primary production (GPP) is the rate at which an ecosystem's producers capture and store a given amount of chemical energy as biomass in a given length of time. Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues.

What is the difference between the primary production and ?

Primary prodution is usually exclusively reserved for plants and autotrophs. Basically anything that can produce energy from sunlight. Plants do not feed on anything, they use sunlight and photosynthesis to create energy. They are the first level

(01.04 MC) Which of the following is a result of lack of visible light at deeper levels in the ocean?

What is net productivity? Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it's the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

What is the unit for gross productivity?

Net primary productivity (NPP) is the rate at which all plants in an ecosystem produce net useful chemical energy. While gross primary productivity (GPP) is the rate at which primary producers save and collect biomass for energy conservation. NPP is the difference between GPP and cellular respiration.

What is Primary Productivity? Primary productivity refers to the degree to which autotrophic organisms (primarily plants and algae) convert energy into organic substances through photosynthesis or chemosynthesis. Since the process of photosynthesis consumes carbon dioxide and produces oxygen, it is of great importance to the environment.
