Best answer: Which land based ecosystem in the figure makes has the highest productivity per square meter?

Which of these ecosystems has the highest primary productivity per square meter?

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 ecosystem on land?

On land the maximum primary production rate is found in tropical rainforests followed by tropical deciduous forests, temperate forests, savannah, temperate grasslands and desert scrub.

Which 3 ecosystems have the highest productivity?

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

What are the two most productive land ecosystems?

The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert. About what percentage of total potential net primary productivity of the entire earth and the earth’s terrestrial ecosystems are used, wasted, or destroyed by humans?

Which terrestrial ecosystem takes up the largest area of land?

Taigas are the world’s largest terrestrial ecosystem and account for about 29% of the Earth’s forests. The largest taiga ecosystems are found in Canada and Russia.

Which of these ecosystems has the highest net primary productivity per square meter annually quizlet?

How is it that the open ocean produces the highest net primary productivity of Earth’s ecosystems, yet net primary productivity per square meter is relatively low? Oceans contain greater concentrations of nutrients compared to other ecosystems. Oceans receive a greater amount of solar energy per unit area.

Which ecosystem is highly productive?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What makes an ecosystem highly productive?

A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. … Trunks and roots trap large amounts of food particles and, once their vital cycle is over, they decompose, thus supplying the ecosystem with more organic matter.

Which ecosystems are most productive?

The most productive ecosystems are fertile estuaries and marshes, coral reefs, terrestrial vegetation on moist alluvial deposits, and intensive agriculture, which can have productivities of 10-25 × 103 kcal/m2/yr.

Which biome has the highest primary productivity per unit area?

As you might expect, the terrestrial biome with the highest level of primary productivity is the tropical rainforest biome with around 2,200 grams of biomass per square meter per year.

Which ecosystem has highest annual net primary productivity?

The tropical rainforest has highest annual net primary productivity (9000 K cal / m2 / yr).

Which ecosystem has highest biomass?

Answer: Forest ecosystem have the maximum biomass, because it includes organisms of all tropic levels as compared to pond, lake or grassland ecosystem.

What are the two most productive land ecosystems and the two most productive aquatic ecosystems?

Tropical forests and swamps are the most productive terrestrial ecosystems. Reefs and estuaries are the most productive aquatic ecosystems. All of these productive areas are in danger from human activity.

Which of the following terrestrial ecosystems is most productive?

Tropical rain forests, with their warm, wet conditions, are the most productive of all terrestrial ecosystems.

What types of ecosystems are Earth’s most productive ecosystems?

Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, fish and mammals can be part of a wetland ecosystem.
