Productivity in an ecosystem
WebbSo then we could also say that this net primary productivity is equal to 2,000 grams per square meter per year times four kilocalories per gram, the grams cancel out, and then … WebbVerified by Toppr Primary productivity is used to describe the rate at which plants and other photosynthetic organisms produce organic compounds or organic matter or biomass in an ecosystem. Primary productivity has two aspects : • Gross productivity = the entire photosynthetic production of organic matter during photosynthesis in an ecosystem.

WebbBacteria play an important role in the conversion of compounds from the atmospheric gas to the form of the compound taken up by plants. Phosphorus and nitrogen are both required for plant growth. Volcanic eruptions are a major source of non-anthropogenic inputs. Processes include weathering and erosion. Question 16. WebbThe organisms responsible for primary production are known as primary producers or autotrophs (self-feeders). They form the base of the food chain, and using chlorophyll they alone are able to capture and store energy from the sun through photosynthesis. Various ecosystems differ in their primary productivity.
In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m d ). The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.
