Describe productivity as a unit of ecosystem
Webper unit area over a time period by plants during photosynthesis. It is expressed in terms of weight (g –2 ) or energy (kcal m–2 ). The rate of biomass production is called productivity. It is expressed in terms of g –2 yr –1 or (kcal m–2 )yr –1 to compare the productivity of different ecosystems. WebFor example, in a forest ecosystem, trees occupy the top level, shrubs occupy the second and the herbs and grasses occupy the bottom level. Components of a Forest Ecosystem. The components of a forest ecosystem are as follows: 1.Productivity. The basic requirement for any ecosystem to function and sustain is the constant input of solar …

WebProductivity can be defined for any trophic level or other group, and it may take units of either energy or biomass. There are two basic types of productivity: gross and net. To illustrate the difference, let's consider primary productivity—the productivity of the primary producers of an ecosystem. WebSo the functional units of an ecosystem or functional components that work together in an ecosystem are: Productivity – It refers to the rate of biomass production. Energy flow – It is the sequential process through which …
WebEcological efficiency is a combination of several related efficiencies that describe resource utilization and the extent to which resources are converted into biomass.
