Is Deep Sea least productive ecosystem?

-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. The average productivity of an ocean ecosystem is about 50 grams of carbon per square meter per year.

Is Deep Sea 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 is the most productive ecosystem?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

Which is correct least productive ecosystem is desert and deep lake?

In an ecosystem, the productivity is the rate of generation of biomass in the given ecosystem in a given time. The least productive ecosystems are deserts and deep lakes.

Which of the following is the least productive biome?

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 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 aquatic habitat is the most productive?

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.

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 biome?

Freshwater wetlands are submerged in water for part of or all of the year, but they are shallow enough to support emergent vegetation. Even though they look nasty, these freshwater wetlands are one of the most productive biomes.
