<onlyinclude>An '''ecosystem''' is a community of different species interacting with one another and their physical [[environment]].<ref name=hackett1>G. Tyler Miller, Jr. and D. Hackett, "Ecosystems," in ''Living in the Environment'', 2nd ed. USA: Nelson , 2011, ch.4, pp.55-86</ref> Depending on the focus of interest or study the extent of an ecosystem may range from very small spatial scales, such as a small pond, to the entire planet.</onlyinclude><ref name=IPCC_SRREN> Verbruggen, A., W. Moomaw, J. Nyboer, 2011: Annex I: Glossary, Acronyms, Chemical Symbols and Preﬁxes. In IPCC Special Report on Renewable Energy Sources and Climate Change Mitigation [O. Edenhofer, R. Pichs- Madruga, Y. Sokona, K. Seyboth, P. Matschoss, S. Kadner, T. Zwickel, P. Eickemeier, G. Hansen, S. Schlömer, C. von Stechow (eds)], Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA.</ref> These systems may be natural (forests, deserts, ponds) or man-made (crop fields, fish farms, reservoirs).

Many factors affect ecosystems and their ability to survive, with the main 3 being:<Ref name=hackett1/>

*'''The Sun''' - nearly all of the [[energy]] available on Earth once originated in the depths of the [[sun]]. It provides high-quality energy for all beings on Earth.
*'''Cycles of matter and energy''' - energy flows throughout the Earth in the form of [[heat]], [[light]] and [[kinetic energy|motion]]. Matter also flows throughout the Earth, including [[water]], [[oxygen]] and other [[molecule]]s. There are many of these cycles, including the [[carbon cycle]], [[hydrologic cycle]], and the [[oxygen#Oxygen on Earth|oxygen cycle]].
*'''Gravity''' - the [[atmosphere]] is held in place by the Earth's [[gravity]], which causes the downwards flow of chemicals in the matter cycles.

The delicate balance of the [[solar energy to the Earth]] allows the ecosystems on Earth to thrive. See [[Earth's heat balance]] for more information.

==Components of ecosystems==

The collection of all ecosystems is known as the '''[[biosphere]]'''. It can be separated into two categories, '''biomes (land)''' and '''aquatic life zones (water)'''. Within these two categories are '''abiotic''' and '''biotic''' entities, the former being non-living components of an ecosystem, such as water, air and nutrients, while the latter is all biological components, from plankton to humans.<Ref name=hackett1/>

===Biomes===
:''[[biome|main article]]''

Biomes are large regions of the terrestrial portion of the biosphere. They include forests, deserts, grasslands and tundras. Biomes are characterized by a distinct [[climate]] and specific species of plants and animals.<ref name=hackett1/>

===Aquatic life zones===

Aquatic life zones contain many ecosystems, such as freshwater zones (lakes and streams) and ocean zones (coral reefs and deep ocean), both of which can be divided up even further. Many factors affect the types of ecosystems in aquatic zones, including, but not limited to:<ref>Harding University. (Accessed August 31, 2015). ''Aquatic Life Zones'' [Online], Available: http://www.harding.edu/doran/aquatic%20life%20zones.htm</ref>

*Availability of [[sunlight]]
*Distance from shore
*Water depths
*Underwater flows
