Describe productivity as a unit of ecosystem
WebProductivity is a rate function, and is expressed in terms of dry matter produced or energy captured per unit area of land, per unit time. It is more often expressed as energy in calories/cm 2 /yr or dry organic matter in g/m 2 /yr (g/m 2 x 8.92 = lb/acre). Hence, the productivity of different ecosystems can be easily compared.

WebPrimary productivity: Productivity in the ecosystem is given as the rate at which energy is consumed by living organisms in the form of biomass. Productivity can be measured for any trophic level in a biomass pyramid and can be given in units of energy or biomass. Productivity is classified into two types, namely gross productivity and net ... WebMay 20, 2024 · In marine ecosystems, primary productivity is highest in shallow, nutrient rich waters, such as coral reefs and algal beds. To show the flow of energy through ecosystems, food chains are sometimes drawn as energy pyramids. Each step of the pyramid represents a different trophic level, starting with primary producers at the bottom.

WebMay 20, 2024 · An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as a biotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. 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.
