statement 1 is correct
Also, terrestrial ecosystems are generally more difficult because a substantial proportion of total productivity is shunted to below-ground organs andAn ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in twoaquatic ecosystem metabolism in lakes, can be expressed as net ecosystem productivity (NEP), the difference between gross primary productivity (GPP) andAn aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic
statement 1st is correct one
hope this helps u
The amount of Biomass produced per unit area by the plants in a community is called the primary productivity of that community.It is expressed either in units of energy or dry organic matter or carbon.The total fixation of energy by the process of photosynthesis is referred to as gross primary productivity and the proportion that is left after respiration losses is called net primary productivity.
The factors that affect primary productivity are the amount of plants present, number of primary consumers and the amount of solar energy, nutrients available in the ecosystem.
Write the equation that helps in deriving the net primary productivity of an ecosystem. [Delhi 2013]
How is the net primary productivity of an ecosystem derived?
Explanation: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.please make it brainlist answer please
hey buddy ..
both statements are correct and second statement is the correct explaination of the first ...
therefore .. option 1..
hooe it helps.
Net Primary Productivity (NPP) is given by Gross Primary Productivity minus Respiration loses (R).
Hence, the equation for deriving NPP is given by:-
NPP = GPP - Rmark as brainliest
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.
I hope it will help you
