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

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

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 ecosystem has highest productivity?

In terrestrial ecosystems, tropical rainforests have the highest productivity.

What has the lowest ecosystem productivity?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.

Which ecosystem has the lowest relative productivity?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome. Which marine ecosystem has average net primary productivity comparable to a tropical rainforest?

THIS IS UNIQUE:  Why do we need to study environmental microbiology?

Which is the smallest ecosystem?

The Temperate Grassland is the smallest ecosystem in the world as well as on earth. The area of this grassland occupied by Tundra.

Are ecosystems least productive?

Least productive ecosystem is desert and deep lake.

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.

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 of the following has the lowest mean net primary productivity?

The correct answer is Temperate grasslands. Temperate grasslands are characterized as having grasses as the dominant vegetation. Trees and large shrubs are absent, therefore it has the lowest mean net productivity in the category of grasslands.

Which of these ecosystems 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.

Why is productivity of tundra biome very low?

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.

Which biome has the highest biodiversity the lowest why?

Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least.

THIS IS UNIQUE:  Question: What will happen if biodiversity is loss?

What terrestrial biomes are least productive?

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

What is the marine ecosystem with the lowest NPP?

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.
