Which of the following ecosystems is usually the most productive each year?

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).

Which ecosystem is the most productive?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

Which of the following is the most productive system?

Tropical rainforest :- this forest has high soil moisture , high availability of nutrients so it has high net primary productivity. Hence, they are the most stable ecosystem. Our required answer is tropical rainforest.

Which of the following ecosystem has the highest primary productivity?

Coral reefs ecosystem has the highest gross primary productivity.

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. The presence of some forms of secondary energy can also help to increase the primary productivity rate.

Which world ecosystems are most productive in terms of biomass?

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 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.

Why are coral reefs the most productive ecosystems?

The coral reefs are known to possess the most productive ecosystem on the earth. … The animals living under the coral reefs swiftly filter the water and allow planktonic organisms to grow, and these plankton get enough sunlight to grow.

Which of the following is least productive ecosystem?

Least productive ecosystem is desert and deep lake.

Which ecosystem has highest productivity Upsc?

Tropical rainforest have highest primary productivity and is least in desert.

Which ecosystem produce the highest annual net primary productivity Mcq?

Hence tropical rain forest ecosystem produces the highest annual net primary productivity(NPP).

Which 3 ecosystems have the highest productivity and which 3 have the lowest productivity?

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

Is our biome ecosystem highly productive?

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. The tropical seasonal forests also fall in the range of having high primary productivity.
