Explanation:
In an ecosystem, the rate of production of organic matter during photosynthesis is termed as Gross primary productivity (GPP).
Gross primary productivity (GPP):
GPP is the total amount of organic matter produced by plants through photosynthesis in a given time period. It is the rate of production of organic matter before any of it is used up in respiration or lost as waste.
Secondary productivity:
Secondary productivity is the rate of formation of new organic matter by consumers from the organic matter they have consumed.
Net productivity:
Net productivity is the rate of accumulation of organic matter after respiration losses have been subtracted from the gross primary productivity.
Net primary productivity (NPP):
NPP is the rate at which organic matter is actually incorporated into plant tissues for growth and reproduction after accounting for respiratory losses.
In conclusion, Gross primary productivity (GPP) is the correct answer for the given question as it refers to the total amount of organic matter produced by plants through photosynthesis in a given time period.
