What are the main ecosystems?

ecosystem is a natural unit consisting of an abiotic (inanimate) part of the environment interacting with biotic (living) plants and animals that are adapted to it. On the planet are hundreds of ecosystems divided into primary categories (ie desert) and numerous subcategories (ie the desert of West Australia). The main ecosystems on the planet are marine ecosystems, including Photic Zone (up to 200 m from the surface) and the abysmal plains (ocean floors). The concept of the ecosystem is very similar to the biome concept. bacteria. It is also known as the subsurface lithoautotrophic microbial ecosystem and is one of the least studied ecosystems on Earth, although it is one of the largest. Most of the planet can also be considered as ecosystems influenced by man, because people are so numerous in nature and hit so often that few regions are unaffected.

ecosystems are often defined in terms of primary manufacturers (vegetation) who serve as an ecosystem base and which everything else eats directly (consumers) or indirectly (predators). The harsh proximity of the equator are some of the main ecosystems defined by the vegetation tropical rainforest, subtropical rainforest, coniferous forest, grassland, taig and tundra. These are mixed with mountainous and desert ecosystems, each with its own unique flora and fauna. There are also a number of human main ecosystems such as crops and cities.

The most important terrestrial main ecosystem is the rainforest - rainforests contain more than half of all biodiversity, perhaps up to 80%. Unfortunately, rainforests are also one of the fastest ecosystems deploying, destroyed cleaning land for agriculture. If this soil cleaning is not aggressive, rainforests could disappear by 2100 or earlier.
