What are the land ecosystems?

A terrestrial ecosystem is a land-based community of organisms and the interactions of biotic and abiotic components in a given area. Examples of terrestrial ecosystems include the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts.

Why is land ecosystem important?

Healthy terrestrial ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits. Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air.

What are the characteristics features of land ecosystem?

Characteristics include : 1) Lower availability of water ( as compared to aquatic ecosystems) and the consequent importance of water as a limiting factor. 2) Greater temperature fluctuations on both a diurnal and seasonal basis. 3) There is greater availability of light favoured by a transparent atmosphere.

What is ecosystem function?

Fundamentally, ecosystem functions are exchange of energy and nutrients in the food chain. These exchanges sustain plant and animal life on the planet as well as the decomposition of organic matter and the production of biomass.

What is the human use of the land or ecosystem?

Ecosystems provide a variety of benefits to people, including provisioning, regulating, cultural, and supporting services. Provisioning services are the products people ob- tain from ecosystems, such as food, fuel, fiber, fresh water, and genetic resources.

What are ecosystem functions?

Ecosystem function is the capacity of natural processes and components to provide goods and services that satisfy human needs, either directly or indirectly (de Groot et al 2002). Ecosystem functions are conceived as a subset of ecological processes and ecosystem structures.

What are the two main categories of ecosystems?

Natural ecosystems are basically classified into two major types. They are aquatic ecosystem and terrestrial ecosystem.

Why land is called ecosystem?

A land, or terrestrial, ecosystem is all the living organisms and their physical environment on a particular piece of land. Terrestrial ecosystems may interact and overlap with marine (salt-water) and limnological (fresh-water) ecosystems. A number of terrestrial biomes can be used to classify smaller ecosystems.

Which land based ecosystem has the most biodiversity?

tropical forests
Worldwide, the tropics contain the most biodiversity, with rainforests being the areas that are the most rich in species. Although the tropical forests only cover 6% of the Earth’s surface, they contain one half to three quarters of the world’s plant and animal species.
