Definition of Ecosystem
An ecosystem is a biological community of interacting living things and their environment. In an ecosystem plants, animals and human beings exist together and depend upon each other for their survival.
OR
An ecosystem is generally an area within the natural environment in which physical (abiotic) factors of the environment, such as rocks and soil, function together along with interdependent (biotic) organisms, such as plants and animals, within the same habitat.
Explanation of Ecosystem
Ecosystems can be permanent or temporary. Ecosystems usually form a number of food webs. Living plants provide food, oxygen and shelter, while dead plants are used as a great source of fossil fuels. Animal provide carbon dioxide used by plants during photosynthesis and excretory waste used as manure for plants. Dead animals decompose to provide basic soil continents. Vital balance is required for survival of all components, malfunctioning can disturb the balance of ecosystem.
Examples of Ecosystem
* Agroecosystem
* Aquatic Ecosystem
* Chaparrel
* Coral Reef
* Desert
* Forests
* Human Ecosystem
* Marine Ecosystem
* Littoral Zone
* Prairie
* Pond Ecosystem
* Rainforest
* Savanna
* TundraUrban Ecosytem
Biomes
Biomes are similar to ecosystems, climatically and geographically defined area of ecologically similar climatic conditions such as communities of plants, animals and soil organisms, often referred to as ecosystems. Biomes are defined based on factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation.
Biodiversity
Biodiversity is the variation of life forms within a given ecosystem, biome, or for the entire earth. Biodiversity is often used as a measure of the health of biological systems. The biodiversity found on Earth today consists of millions of distinct biological species, which is the product of nearly 3.5 billion years of evolution. 2010 is the International Year of Biodiversity.
Functions of Ecosystem
From an anthropological point of view, some people perceive ecosystems as production units that produce goods and services, such as wood by forest ecosystems and grass for cattle by natural grasslands. Meat from wild animals, often referred to as bush meat in Africa, has proven to be extremely successful under well-controlled management schemes in South Africa and Kenya. Much less successful has been the discovery and commercialization of substances of wild organism for pharmaceutical purposes. Services derived from ecosystems are referred to as ecosystem services. They may include:
* Facilitating the enjoyment of nature, which may generate many forms of income and employment in the tourism sector, often referred to as eco-tourisms.
* Water retention, thus facilitating a more evenly distributed release of water.
* Soil protection, open-air laboratory for scientific research, etc.
