What do you mean by ecosystem productivity?
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).
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 is an example of a productive ecosystem?
High productivity ecosystem: For example, tropical forests, flood plains, coral reefs, areas of upwelling, sugar cane fields, etc. Average productivity ecosystem: For example, common agricultural crop and temperate forest. Less productivity ecosystem: For example, grassland ecosystem and savannah.
What is ecosystem productivity explain the different types of ecosystem productivity?
Productivity in ecosystems is of two kinds, i.e., primary and secondary. Green plants fix solar energy and accumulate it in organic forms as chemical energy. As this is the first and basic form of energy storage, the rate at which the energy accumulates in the green plants or producers is known as primary productivity.
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 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 is productivity in bio?
The amount and rate of production which occur in a given ecosystem over a given time period. Biological productivity may apply to a single organism, a population, or entire communities and ecosystems.
What is primary productivity of an ecosystem and how is it expressed?
Primary productivity is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis. Primary productivity is expressed in terms of weight (g–2) or energy (kcal m–2 ).
What is productivity and levels in ecosystem?
Productivity within an ecosystem can be defined as the percentage of energy entering the ecosystem incorporated into biomass in a particular trophic level. Biomass is the total mass in a unit area (at the time of measurement) of living or previously-living organisms within a trophic level.
Which 3 ecosystems have the highest productivity?
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 productivity in aquatic ecosystem?
Net marine primary productivity is the amount of organic material available to support the consumers (herbivores and carnivores) of the sea. The standing crop is the total biomass (weight) of vegetation. Most primary productivity is carried out by pelagic phytoplankton, not benthic plants.
