Frequent question: Which ecosystems show the highest average net primary productivity and which contribute most to global net primary productivity?

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

What are the 3 ecosystems that have the highest net primary productivity on Earth?

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). Figure 4. Net Primary Production per unit area of the world’s common ecosystems.

Which of the ecosystems below has the highest primary productivity?

Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes. Net primary productivity ranges from 2–3 kg m2 y1 or higher.

What is the most productivity ecosystem in the world?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

Which of of the following ecosystem has the highest net primary productivity per square meter?

Tropical rain forests occur over equatorial/ subequatorial regions with abundant warmth and rainfall. Diversity and productivity are maximum as ! compared to other regions.

Which 3 ecosystems have the highest productivity?

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 high net primary productivity?

Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it’s the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

Which marine ecosystem has the lowest average net primary productivity?

Main points

  • Marine ecosystems generally have low productivity. …
  • Coral reefs occur in warm, shallow ocean in areas of constant current. …
  • Productivity in continental shelf areas is higher than that in deep oceans.

Which of the following ecosystem has the lowest net primary productivity?

Deserts, tundra, the open ocean, and the lakes and streams biome all have the lowest amounts of primary productivity.

Which ecosystem is most productive in terms of net primary production?

In terms of net primary productivity tropical rain forest is at the top followed by coral reef, easturies and desert and ocean.

Which ecosystem has highest biomass productivity?

Answer: Forest ecosystem have the maximum biomass, because it includes organisms of all tropic levels as compared to pond, lake or grassland ecosystem. In forest ecosystems productivity is also high that contributes to maximum biomass.

Which ecosystem produce the highest annual net primary productivity Mcq?

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