What is productivity and its types in an ecosystem?

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−2 d−1). The unit of mass can relate to dry matter or to the mass of generated carbon.

What is productivity in an ecosystem?

Productivity in an ecosystem refers to the percentage of energy that enters the ecosystem in the form of biomass at a particular trophic level. It is the rate at which biomass is formed in the ecosystem. At each trophic level in the ecosystem, a characteristic amount of biomass is present.

What are the 3 most productive types of ecosystems?

The world’s ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests (see Figure 4).

What is meant by productivity?

Productivity is commonly defined as a ratio between the output volume and the volume of inputs. In other words, it measures how efficiently production inputs, such as labour and capital, are being used in an economy to produce a given level of output.

What are the types of primary productivity?

In ecology, primary productivity means the rate at which the energy is converted into organic substances with the help of photoautotrophs and chemoautotrophs. It is further divided into 2 types: 1) Net primary productivity, 2) Gross primary productivity.

Why is productivity important to an ecosystem?

The productivity of the primary producers ( gross primary productivity ) is important to ecosystems because these organisms bring energy to other living organisms.

What is productivity in aquatic ecosystem?

The productivity of aquatic systems has been given two meanings in the literature: either the transfer of matter or energy through the food web, or the quantity of fish that may be captured in a sustainable way per unit of time. A number of short-cuts may be used to estimate the sustainable fish catch.

Which ecosystem has the highest productivity?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What 3 ecosystems have the lowest productivity?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
