What do productive ecosystems include?
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). Figure 4. Net Primary Production per unit area of the world’s common ecosystems.
What are the types of ecosystem productivity?
According to Odum there are three types of productivities – primary productivity, secondary productivity and community productivity.
What ecosystem is most productive?
Tropical rainforests show the highest productivity in terrestrial ecosystems.
What are the major productivity functions of ecosystem?
The productivity of an ecosystem refers to the rate of production, i.e., the amount of organic matter accumulated in any unit of time. It is of three types, viz., primary, secondary and net productivity.
What do you mean by productivity of an ecosystem What are the types of productivity also mention the factors on which productivity of an ecosystem depends?
In ecology, productivity refers to the rate of formation of biomass in the ecosystem. It can also be referred to as the energy accumulated in the plants by photosynthesis. There are two types of productivity, namely: Primary Productivity. Secondary Productivity.
What are the 3 most productive and 3 least productive ecosystems?
The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.
Why is productivity important to an ecosystem?
Ecosystems have characteristic amounts of biomass at each trophic level. … The productivity of the primary producers is especially important in any ecosystem because these organisms bring energy to other living organisms by photoautotrophy or chemoautotrophy.
What is the concept of 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.
