Which aquatic ecosystem has the highest NPP?

coral reefs
In the aquatic ecosystem, coral reefs show the highest gross primary productivity. Large numbers of aquatic phototrophs and phytoplankton contribute to the productivity of the ecosystem.

Which kinds of ecosystems have the highest NPP Why?

Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. The physical environment favours vast photosynthetic output and high growth rate.

What 3 ecosystems have the highest productivity?

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 lowest NPP?

About 40 to 85 percent of gross primary productivity is not used during respiration and becomes 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 ecosystems have the highest productivity?

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

Which ecosystems have the highest productivity?

How do you find NPP?

You can see that your bank account balance is determined as follows: Your Net production is equal to your Gross Production minus Respiration, which is the same as the equation above that states the Net Primary Production (NPP) = the Gross Primary Production (GPP) minus Respiration (R).

What three tropical ecosystems have the highest primary productivity?

What is NPP a measure of?

Net primary production (NPP) is a measure of the annual productivity of the plants in the biosphere.

How do you calculate NPP examples?

What ecosystem has the highest productivity?

Which is an ecosystem with the highest NPP?

Key Words: Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. The physical environment favours vast photosynthetic output and high growth rate.

What is the net productivity of an aquatic ecosystem?

aquatic ecosystems In marine ecosystem: Biological productivity …of producers; what remains is net productivity. Net marine primary productivity is the amount of organic material available to support the consumers (herbivores and carnivores) of the sea.

Which is the most productive ecosystem in the ocean?

It is thus not surprising that the most productive natural aquatic plant communities are benthic. In marine waters the most productive systems are brown algal beds, seagrass beds and coral reefs.

Why do rain forests have a high NPP?

Main points Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. In rain forests, plants have constant high levels of water and light (at canopy level) and the nutrient supply is as high as possible, due to rapid decomposition.
