What are the functions of an ecosystem? What is ecosystem diversity?

The co-evolution between organisms and between organisms and inorganic environments forms biodiversity. In this sense, protecting biodiversity is an important point, that is, protecting the diversity of ecosystems. Ecosystem diversity is the guarantee of species diversity. What are the functions of ecosystems? Do you know?

What are the functions of an ecosystem?

1. Energy flow: refers to the process of energy input, transfer, transformation and loss in an ecosystem. Energy flow is an important function of an ecosystem. In an ecosystem, the close connection between organisms and the environment, and between organisms, can be achieved through energy flow.

2. Material cycle: The energy flow of the ecosystem drives the circulation of various substances between the biological community and the inorganic environment. The substances here include the basic elements that make up organisms: carbon, nitrogen, sulfur, phosphorus, and toxic substances such as DDT that can exist stably for a long time.

3. Information transmission: including physical information, chemical information, and behavioral information.

What is ecosystem diversity?

Ecosystem diversity refers to the degree of ecological diversity in an area. It is different from species diversity, which refers to the types of species rather than ecosystems.

Ecosystem diversity refers to the variation and frequency of different ecosystems. It refers to the diversity of habitats, biomes and ecological processes within the biosphere, as well as the diversity of habitat differences and ecological changes within the ecosystem. Ecosystem diversity can refer to the diversity of ecosystem levels in a region, or the various ecosystems in a biosphere.

Ecosystem diversity is the guarantee of species diversity. Any organism must live in a certain environment. Without a suitable environment, it is difficult for organisms to adapt.

Therefore, only diverse ecosystems can guarantee the survival of a variety of organisms in these ecosystems. In this sense, an important point in protecting biodiversity is to protect the diversity of ecosystems, and ecosystem diversity is the guarantee of species diversity.

The co-evolution between organisms (of the same species or different species) and between organisms and the inorganic environment forms biodiversity (including species diversity, genetic or genetic diversity, and ecosystem diversity).

What is the largest ecosystem in the world?

The biosphere refers to all parts of the atmosphere from 10km above the horizon to the ocean from 10km below. It includes the atmosphere, lithosphere and oceanosphere. As the largest ecosystem in the world, the biosphere also contains a variety of ecosystems, or more precisely, it is composed of a variety of ecosystems. It consists of two artificial ecosystems, urban ecosystems and farmland ecosystems, as well as forest ecosystems, grassland ecosystems, lake (freshwater) ecosystems, desert ecosystems, sparse tree ecosystems, mountain ecosystems, wetland ecosystems, marine ecosystems and other ecosystems.
