What world ecosystem have high net productivity?

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

What ecosystem has highest net productivity?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What is a high productivity ecosystem?

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).

Where is the most productive ecosystem?

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.

What world ecosystem have high net productivity Why?

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

Which ecosystem has highest annual net primary productivity?

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

What is net 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.

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.

Which aquatic ecosystem has the highest net primary productivity?

In general, swamps and marshes have the highest primary production of all the world’s ecosystems. Primary production of all wetland types varies from 600-2000 gC/m2/y.

What ecosystems are the least productive in the world?

The least productive ecosystems are those limited by heat energy and water like the deserts and the polar tundra. The most productive ecosystems are systems with high temperatures, plenty of water and lots of available soil nitrogen.

Which is the world’s most productive ecosystem in terms of biomass?

Which of the following is among the world’s most productive ecosystems in terms of biomass production? Explanation: Brackish water ecosystems in river deltas are covered by mangrove forests and are among the world’s most productive ecosystems in biomass production.

Which of the following is one of the most productive ecosystems on Earth?

Coral Reef Ecosystems

IMPORTANT:  Which of the following is are measures of biodiversity in an ecosystem?

“Due to their structural complexity, corals are one of the most productive ecosystems on Earth,” states Mongabay. Often called rainforests of the ocean, they support a wide diversity of marine life in various stages of growth.

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.

Which season has the highest NPP?

In mid-latitudes, productivity is obviously tied to seasonal change, with productivity peaking in each hemisphere’s summer. The boreal forests of Canada and Russia experience high productivity in June and July and then a slow decline through fall and winter.
