Which Is The Most Productive Ecosystem?

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..

Which is the largest ecosystem on earth?

The World OceanThe World Ocean is the largest existing ecosystem on our planet. Covering over 71% of the Earth’s surface, it’s a source of livelihood for over 3 billion people.

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 are the two most productive land ecosystems?

The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert. About what percentage of total potential net primary productivity of the entire earth and the earth’s terrestrial ecosystems are used, wasted, or destroyed by humans?

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 is the smallest ecosystem in the world?

The smallest land areas are occupied by tundra and temperate grassland ecosystems, and the largest land area is occupied by tropical forest. The most productive ecosystems are temperate and tropical forests, and the least productive are deserts and tundras.

What is the least productive biome?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.

Which ecosystem is highly productive?

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 is the most productive ecosystem or biome on this planet?

Tropical forestsTropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

Is the world an ecosystem?

Although it is well accepted that Earth consists of many different ecosystems, human societies much less readily recognize that Earth itself is an ecosystem, dependent on interacting species and consisting of finite resources.

What is the largest saltwater ecosystem?

Great Barrier ReefCoral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef.

What is the best biome for humans to live in?

DesertsIt also has interesting activities like matching precipitation graphs with locations and matching different plant life with the right biome. Deserts seem to be the most inhospitable biome for humans but humans have been able to adapt to desert life for hundreds of years.

What is the coldest biome?

tundraThe tundra is the coldest of the biomes. It also receives low amounts of precipitation, making the tundra similar to a desert. Tundra is found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia.
