Which two continental ecosystems are most productive?

Which two marine ecosystems are 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 are the top 4 most productive continental ecosystems?

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 terrestrial ecosystem has the highest productivity?

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 3 ecosystems have the lowest productivity and which 3 have the lowest productivity?

Primary productivity is a term used to describe the rate at which plants and other photosynthetic organisms produce organic compounds in an ecosystem. . The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.

Which is the most productive aquatic biome?

When the water is relatively clear, photosynthesis can occur in the neritic zone. The water contains silt and is well-oxygenated, low in pressure, and stable in temperature. These factors all contribute to the neritic zone having the highest productivity and biodiversity of the ocean.

What ecosystem has the lowest productivity?

Deserts, tundra, the open ocean, and the lakes and streams biome all have the lowest amounts of primary productivity.

Which of the following ecosystems is usually the most productive each year?

Mangrove Forest Ecosystems

Mangrove forests are among the most productive ecosystems on the planet. They store large amounts of nutrients which feed multiple species of mollusks, fish and crustaceans. These attract various predators that also use mangroves for shelter and nurseries.

Is our biome ecosystem highly productive?

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. The tropical seasonal forests also fall in the range of having high primary productivity.

Which terrestrial or oceanic community have the greatest productivity?

In terrestrial ecosystems, primary productivity is highest in warm, wet places with plenty of sunlight, like tropical forest regions. In contrast, deserts have the lowest primary productivity. In marine ecosystems, primary productivity is highest in shallow, nutrient rich waters, such as coral reefs and algal beds.

Which ecosystem produce the highest annual net primary productivity *?

Hence tropical rain forest ecosystem produces the highest annual net primary productivity(NPP).
