Which ecosystem can be included in least productive category?

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 ecosystem has least productivity?

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.

What is the most productive type of ecosystem?

In an ecosystem, primary productivity refers to the accumulation of energy in terms of biomass. In aquatic ecosystems, coral reefs have the highest productivity. Tropical rainforests show the highest productivity in terrestrial ecosystems.

Which world ecosystems are most productive in terms of biomass which are the least productive?

What units are used in this figure to quantify biomass accumulation? The most productive ecosystems are tropical rain forests and estuaries. The least productive ecosystems are desert and open ocean. The units to quantify biomass accumulation are 1,000/kcal/m2/year.

Is Deep Sea least productive ecosystem?

The primary factors affecting the productivity of any ecosystem are sunlight, carbon dioxide, water, and nutrients. … -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 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. These biomes include habitats that have extreme temperatures and very limited precipitation, which results in very low production of new biomass.
