Terrestrial Ecosystem and its Occupation on Earth Surface

Ruibo HAN

A terrestrial ecosystem is a type of ecosystem found only on land forms. Six primary terrestrial ecosystems exist: tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, deserts.
A community of organisms and their environment that occurs on the land masses of continents and islands, terrestrial ecosystems are distinguished from aquatic ecosystems by the lower availability of water and the consequent importance of water as a limiting factor. Terrestrial ecosystems are characterized by greater temperature fluctuations on both a diurnal and seasonal basis that occur in aquatic ecosystems in similar climates.
Terrestrial ecosystems are of particular importance especially in meeting sustainable development goal 15 that targets the conservation restoration and sustainable use of terrestrial ecosystems.
