Which of the following ecosystem is least productive?
Least productive ecosystem is desert and deep lake.
Which of the following is least productive ecosystem desert?
Very low productivity is present in deserts and arctic regions. In oceans and other aquatic ecosystems, productivity is limited by light as it decreases with depth. But on a global basis, aquatic ecosystems occupy more space on earth than any other biome and have good productivity in surface layers, which are euphotic.
Which of the following ecosystem can be included in least productive category?
The least productive ecosystems are deserts and deep lakes.
Is sugarcane field a productive ecosystem?
The most productive ecosystem are coral reef ecosystem due to structural complexity. It is also called as tropical rain forests. It includes temperate and tropical forests. … Sugarcane is the most productive agroecosystem.
Are coral reefs least productive ecosystem?
In oceans, there are lots of nutrients but no sufficient sunlight is available in deep areas hence, oceans have least productivity. Grasslands are less productive ecosystem with annual productivity of 200-100gm/m2. Maximum productivity can be seen in coral reefs followed by estuaries.
Which of the following is most productive ecosystem?
Tropical rainforest shows the maximum diversity and also the maximum productivity.
Which of the following ecosystem is least productive in terms of net primary productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Is Deep Sea a productive ecosystem?
Upwelling. The most productive waters of the world are in regions of upwelling. Upwelling in coastal waters brings nutrients toward the surface. Phytoplankton reproduce rapidly in these conditions, and grazing zooplankton also multiply and provide abundant food supplies for nekton.
Why are tropical wet forests and estuaries most productive?
Tropical Rainforests have high primary productivity because of availability of plenty of solar light and water. A typical estuary has high primary productivity because it is shallow (gets plenty of sunlight) and has turbulent water (which brings the nutrient rich material from sea bed).
What is an ecosystem Ncert?
SUMMARY. An ecosystem is a structural and functional unit of nature and it comprises abiotic and biotic components. Abiotic components are inorganic materials- air, water and soil, whereas biotic components are producers, consumers and decomposers.
What is high net primary productivity?
A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. … The presence of some forms of secondary energy can also help to increase the primary productivity rate.
