Your question: What world ecosystem have high and low net productivity?

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

Which ecosystem has the highest productivity?

In terrestrial ecosystems, tropical rainforests have the highest productivity.

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 ecosystems are the least productive in the world?

The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.

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 of the following ecosystem has the highest net primary productivity?

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

IMPORTANT:  How do you collect recycled materials?

Which of the two types of ecosystem net productivity is high?

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.

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 would have the highest net primary production 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.

What is high net primary productivity?

The primary productivity of an ecosystem is defined as the speed at which the solar energy is turned into an organic substance by chlorophyll in the photosynthesis. … A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable.
