Which of the following ecosystems can be included in least productive coral reef desert tropical rain forest sub tropical forest?

Which ecosystem will have least productivity?

-Oceans contain lots of nutrients but they have no sufficient sunlight reaching in the deep areas, therefore, oceans have the least productivity among all ecosystems.

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 ecological habitats is considered as least productive?

The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.


Producer Biomass productivity (gC/m²/yr)
Coral reefs 2,000
Algal beds 2,000
River estuaries 1,800
Temperate forests 1,250

Which of the ecosystem is most productive?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

Which ecosystem has lowest net primary productivity?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.

Which of the following ecosystem is least productive in terms of net primary production?

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

Are deserts the least productive ecosystem?

Least productive ecosystem is desert and deep lake.

Is Deep Sea a productive ecosystem?

They estimate that worldwide, deep-sea hydrothermal vent microbial communities can produce more than 4,000 tons of organic carbon each day, the building block of life. That is roughly the same amount of carbon in 200 blue whales — making these ecosystems among the ocean’s most productive on a per volume basis.

Which of the given is are among the most productive ecosystem coral reefs sugarcane field desert both 1 and 2?

Sugarcane is the most productive agroecosystem. Thus, the correct answer is ‘All of the above.

What makes an ecosystem productive?

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.

Is Coral Reef productive ecosystem?

Coral reefs are among the most productive ecosystems on the planet, with the primary producers at the base of the food chain (including corals) supporting their complex food webs. … Although light provides the energy that fuels reef productivity, key nutrients such as nitrogen and phosphorus are also required.

IMPORTANT:  What are the three classifications of climate?

What are the three most productive 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 the most productive aquatic ecosystem?

It is thus not surprising that the most productive natural aquatic plant communities are benthic. In marine waters the most productive systems are brown algal beds, seagrass beds and coral reefs.
