Question: What Are The Two Most Productive Land Ecosystems?

Which of the following ecosystem has the highest primary productivity?

Coral reef ecosystemCoral reef ecosystem has highest gross primary productivity due to availability of large number of autotrophs per unit area..

What happens to matter in an ecosystem?

In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

Where are the most productive marine ecosystems found?

Although they occupy just fewer than two percent of the surface of the oceans, the large coastal upwelling areas on the eastern edges of the Pacific and the Atlantic are among the most biologically productive marine areas of all.

Which part of the ocean is most productive?

CoastalYet this relatively small sliver of ocean contains about half of all the microscopic plants adrift in our seas. With satellites we can see what fishermen find with their nets: Coastal waters are the most biologically productive portions of the world’s oceans.

Which ecosystem is known as giant permanent pond?

lake ecosystemWhich ecosystem is known as giant permanent pond? Explanation: A lake ecosystem functions like a giant permanent pond. A large amount of its plant material is algae.

Which ecosystem has the highest biodiversity?

Coral reefsCoral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than twenty-five percent of marine life.

Which ecosystems are most productive?

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).

Which two marine ecosystems are the most productive?

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.

What 3 ecosystems have the lowest productivity?

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

What is the world’s largest floating ecosystem?

neritic zoneThe world’s largest floating ecosystem is the neritic zone.

What is true ecosystem?

An ecosystem may be defined as a structural and functional unit of the biosphere comprising living organisms and their non-living environment that interact by means of food chains and chemical cycles resulting in energy flow, biotic diversity and material cycling to form a stable, self supporting system.

What are the 2 main types of ecosystem?

There are two types of ecosystem:Terrestrial Ecosystem.Aquatic Ecosystem.
