You asked: What two terrestrial ecosystems have the highest NPP?

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

What two ecosystems contribute the most to NPP?

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 following ecosystems has the highest NPP per unit area?

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 increases NPP in terrestrial ecosystems?

In general, terrestrial ecosystem net primary production increases with increasing: moisture availability as measured by evapotranspiration. length of growing season. temperature measured as mean annual temperature.

What biome has the highest NPP?

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 terrestrial biome has the highest net primary productivity per unit area?

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.

Which terrestrial and aquatic ecosystems have the highest NPP Why do you think this is?

AP Chapter 54 – Ecosystem Ecology (detailed)

A B
Which terrestrial ecosystem has the highest average net primary productivity? tropical rain forests.,
Which freshwater ecosystem has the highest average net primary productivity? swamps and marshes,

Which of the following ecosystem has the highest?

Coral reefs ecosystem has the highest gross primary productivity.

Which of the following best describes a terrestrial ecosystem that will have the highest net primary productivity?

Which of the following best describes a terrestrial ecosystem that will have the highest net primary productivity? Net primary productivity is highest in areas where temperatures are warm and water and solar energy are abundant and encourage the growth of producers.

Why do tropical rainforests and marshes have high NPP?

In Tropical Rainforests, water, sunlight, and high temperatures are consistent and a dense concentration of plants is present, causing both the GPP and NPP to be very high. So, high levels of productivity increase biomass.

What is terrestrial NPP?

The growth over time of all plant tissues within a terrestrial ecosystem is equal to NPP. In this approach, aboveground (ears, stalks, leaves) and belowground (roots) corn biomass yield over a single growing season is equal to annual NPP of this crop 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.
