Which of the following ecosystem can be included in least productive category? ›

In an ecosystem, the productivity

Deserts, tundra and the open ocean are the least productive ecosystems typically having less than 0.5 x 10³ kcal.

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

Among the given options, desert has the least productivity because it supports least life campare to the other options. While tropical forest and coral reef support many life forms and have high productivity.

Least productive ecosystem is desert and deep lake.

What ecosystems have the least amount of productivity per unit area? Tundras, the open ocean, desert scrubs, and the extreme desert.

The tundra has some of the lowest net primary productivity of any ecosystems, due mainly to the cold and short growing season, and the infertile soils. Mean productivities range from 10-400 g m^-2 yr^-1, with a mean of 140 g m^-2 yr^-1.

Answer and Explanation:

Desert ecosystems are the ecosystems with the lowest net primary productivity. Deserts are ecosystems characterized by low levels of precipitation.

-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.

Tundra Biome

Because of these low temperatures and short growing seasons, net primary productivity is very low in the tundra, between 100–200 g m^-2 yr^-1.

Why is the ocean the least productive ecosystem? ›

In aquatic ecosystems, the limiting factor for productivity is light as the producers depend on the light which is scanty in deeper layers. The availability of nutrients present in the ocean is less.

Answer and Explanation:

The aquatic biomes that are the least productive are the open ocean, the hadopelagic zone of the ocean, and the Dead Sea.

Answer and Explanation: The bog freshwater ecosystem is the least productive. This is because bogs drain poorly, meaning that soil becomes too saturated to support nutrients, which leech out into the water.

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.

The following ecosystems are so as of their net primary productiveness, from lowest to the maximum is open ocean, tropical rain woodland, wasteland, and lake.

Desert and Tundra Biomes, limited by precipitation and temperature respectively, contain the least productive ecosystems.

Freshwater ecosystems are the least common, occurring on only 1.8 percent of Earth's surface. These systems comprise lakes, rivers, streams, and springs; they are quite diverse and support a variety of animals, plants, fungi, protists and prokaryotes.
