Your question: What are the types of ecosystem productivity?

According to Odum there are three types of productivities – primary productivity, secondary productivity and community productivity.

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 ecosystem productivity?

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 is primary and secondary productivity in ecosystem?

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.

What are the three fundamental concepts of productivity of an ecosystem?

Article shared by : ADVERTISEMENTS: Productivity of Ecosystem: Primary, Secondary and Net Productivity! The productivity of an ecosystem refers to the rate of production, i.e., the amount of organic matter accumulated in any unit time.

Which 4 ecosystems have the highest productivity and which 4 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.

What are the three least productive ecosystems?

Deserts, tundra, and the deep ocean are the least productive ecosystems, typically having an energy fixation of less than 0.5 × 103 kilocalories per square meter per year (thousands of kcal/m2/yr; it takes one calorie to raise the temperature of one gram of water by 34°F [1°C] under standard conditions, and there are …

Why different ecosystems have different productivity?

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.

Which is productive ecosystem?

Which ecosystem is most productive?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What do you mean by secondary productivity?

Secondary productivity is the rate at which the consumers convert the chemical energy of their food into their own biomass is called as secondary productivity. The efficiency at which energy is transferred from one trophic level to another is called as ecological efficiency.

What is net secondary productivity?

NET SECONDARY PRODUCTIVITY. (NSP) • The gain by consumers in energy or biomass. remaining per unit area per unit time after. respiratory losses.

What is primary productivity and its types?

Primary productivity is defined as the amount of energy accumulation in photosynthetic organisms, by the process of photosynthesis, as biomass or organic matter per unit area over a period of time. It varies in different types of ecosystems because of the different factors that influence it.

What is primary productivity example?

The primary productivity of an ecosystem is defined as the speed at which the solar energy is turned into an organic substance by chlorophyll in the photosynthesis. An example is that of estuaries, one of the most productive ecosystems in the world. …
