1. Natural ecosystem
it is classified into two parts
1. Terrestrial ecosystem
Terrestrial ecosystem is a community of organisms and their relationship with environment on the landmasses of Islands and continents. Terrestrial ecosystems account 28.2% of the planet's surface.
All types of forest, deserts, trees, plants, and grasslands etc are said to be terrestrial ecosystem.
Ecosystems which are found on land, air, trees, underground in soil is know as Terrestrial Ecosystem
Few examples are:
* Forest Ecosystem
* Sahara Desert Ecosystem
* A Grassland Ecosystem
* A Semi-forest Ecosystem
* An ecosystem on a snow field
* A Scrubland ecosystem
* A Cold desert ecosystem
* Wetland ecosystem
* Wild Life Sanctuaries, National Parks, Animal Reserves
Forest Ecosystem
Grassland Ecosystem
In a grassland ecosystem, many stands of trees are eradicated by brush fires and dry periods (though single trees and a few tree stands do survive). However, the grasslands, as their name indicates, receive sufficient precipitation to sustain different varieties of grasses. Today, many grasslands are becoming endangered because of farmers allowing their herds of animals to overgraze. The grasslands are subdivided into tropical grasslands (also known as the savannas); temperate grasslands, like the prairies of the Midwest in the United States; and the polar grasslands like the northern Canadian tundra.
Deserts Ecosystem
Deserts are ecosystems with hardy inhabitants, able to survive in an environment that receives less than 25cm of rainfall annually. The desert is home to plants that lie dormant until it rains, then they bloom and spread their seeds, which then lie dormant until the next major rainfall. It is also home to plants capable of storing their own water, such as cacti. Many desert animals survive the searing heat by burrowing or living in caves. These animals are largely nocturnal, staying underground during the heat of the day and foraging for food at night when it is cool.
Mountainous Ecosystems
Mountainous ecosystems can often be home to several smaller ecosystems, including meadows or forest regions. Because of steep elevation changes between peaks and valleys, mountainous regions can be quite varied in their climates. Mountain regions are quite sensitive to human impact.
Ecosystem
An Ecosystem is a combination of two words "Ecological" and " system", that is the collection of biotic and abiotic components and processes that comprise, and govern the behavior of some defined subset to the biosphere.
Ecosystems are composed of organisms interacting with each other and with their environment such that energy is exchanged and system-level processes, such as the cycling of elements, emerge. The ecosystem is a core concept in Biology and Ecology, serving as the level of biological organization in which organisms interact simultaneously with each other and with their environment
An ecosystem is a biological environment consisting of all the organisms living in a particular area, as well as all the nonliving, physical components of the environment with which the organisms interact, such as air, soil, water and sunlight. It is all the organisms in a given area, along with the nonliving (abiotic) factors with which they interact; a biological community and its physical environment
The ecosystem is the combination of a-biotic and biotic components of environment. The ecosystem involves a-biotic environment which is also known as physical environment like rocks, rivers, climate, soil, atmosphere, air etc, and biotic environment like animals human and trees and all living beings. Ecological system or ecosystem is an open space built by physical and biological components of an environment.
The components of ecosystem are biotic component and a-biotic component
Ecosystems are functional units consisting of living things in a given area, non-living chemical and physical factors of their environment, linked together through nutrient cycle and energy flow,Food Chains

Forest Ecosystem
Forests can be divided further into four different subgroups, but all of these have a dense tree population and medium to high levels of precipitation in common. Tropical rain forests are home to a great diversity of animals. The climate is hot with excessive rainfall, and vegetation grows in several layers from the forest floor to the canopy. The forests of India and eastern Brazil, however, have specific seasons of rain and dry weather. These forests are called tropical deciduous forests. Coastal coniferous and temperate deciduous forests flank the west and east coasts of the U.S., respectively. They experience four seasons, and only moderate rainfall. The northern Canadian forests are predominately coniferous and experience long sub-arctic winters.

In a grassland ecosystem, many stands of trees are eradicated by brush fires and dry periods (though single trees and a few tree stands do survive).

2. Aquatic ecosystem
Aqatic ecosystem is a community of organisms that are based on water bodies and maintain relationship with their aqatic environment. Aquatic ecosytem covers approximately 71% of the earth's surface
* This type of ecosystem located in water area located in water area like sea, lake, pond, pools, ditch, river etc.
* It is divided into two parts- Marine ecosystem and freshwater ecosystem. Ecosystem disposes are purifying water, sheltering wild animals and recharging ground water.
* Freshwater, this may be Iotic like stream, river etc and lentic like lake, pond, pools, ditch, swamp etc.
1. Lentic, the ecosystem of a lake, pond or swamp.
2. Lotic, the ecosystem of a river, stream or spring.
A few components of an aquatic ecosystem
pond layers - Like in a forest, the top, middle, and bottom of a pond can be vastly different from each other, and even the layers in between. Under different temperature or light conditions the water in a pond can vary greatly in oxygen, clarity, and other factors that effect were plants and animals might live. The air above the pond and the land below the pond are important as well, as those provide space for animals to live, plants to root, and predators and prey to interact.
diversity - while many people think of a pond as just a small lake with frogs and fish, there are thousands of differents species of plants and animals living together in a natural pond. The more diverse a pond is (more species that it has) the stronger and healthier it is.
micro-organisms - some of the most imortant plants and animals in a pond are so small they are difficult to see without a microscope. They are called "micro-organisms" (micro=small, organism=life form) and while a few may cause disease, almost all are very beneficial and important to a pond ecosystem. While bigger animals may fly, walk, or swim away to other ponds, micro-organisms are always present in large numbers.
macro-organisms - larger plants and animals that are easy to see on a pond are called "macro-organisms (macro=large). They are the plants and animals that we often notice first, and can more easily spread from pond to pond.
Aquatic systems can be found at River Bend
* Marsh - shallow water with non-woody plants growing above water level
* Swamp - like a marsh but with bushes and trees growing from the water as well
* Pond - a small and shallow body of water with plants growing above water level only on the edges; generally freezes solid during winter.
* River - a moving body of water that flows from one place to another.
* Stream - smaller than a river, may even dry up sometimes
* Puddles - and body of water that lasts for a few days or more may attract aquatic life
* Spring - area where underground water is discharged onto the land suface forming a pond or stream
Aquatic systems can be found on Earth
* lake * ocean * creek * lagoon * bog * sea * glacier * tidal pool * geyser * fen
* flood plain * bog * estuary * aquifer * salt lake

3. Artificial ecosystem
Artificial, ecosystems created by humans.
An artificial ecosystem is an ecosystem made by man. An artificial ecosystem is something like an animal reserve or a giant terrarium, one example, a zoo.
* The artificial ecosystem is also known as man-made or man-engineered ecosystems. All types of artificial ecosystems are introduce and managed by man.
* Gardens are also artificial ecosystem that are made and maintained by human. We can add any type of plant according to our likeness in the garden.
Artificial ecosystem are created and maintained artificially by human beings where, by addition of energy and deliberatemanagement, balance of the nature is disturbed regularly, e.g. croplands likemaize, sugarcane, rice-fields, wheat, orchards, villages, gardens, dams, aquarium, cities, and manned spaceship. The basic components biotic and abiotic components are defined by man in artificial ecosystem.
Artificial ecosystems are the ecosystem which are created and maintained by human beings. They are also referred as man engineered ecosystem or man-made ecosystem. The biotic and abiotic components of the artificial ecosystem are defined and maintained by the man.These are maintained by man by addition of energy. Artificial ecosystems disturb the natural balance.
Among the two types of ecosystems artificial ecosytem disturbs the natural balance and causing many adverse effects. eg: ozone depletion, greenhouse effect etc. In order to maintain proper balance in natural environment there should be control of artificial ecosystems. Other wise there will be no more natural ecosystem remains on the planet.
Peril (Risk) Of ecosystems
A food chain shows an energy relationship. A plant captures sunlight and uses it for photosynthesis. Photosynthesis is the process that is happened in plants and tress to make food themselves.
When an insect eats the planet, the insects gets some of the energy. If a bird eats the insects, the energy is transferred to one more time. this is the Energy flow of ecosystems. Fertilizers get in the lake and cause more algae than usual to grow. the increased algae results in the death of evn more members of the community.
Soon, the balanced ecosystem no longer exists. People are changing ecosystems like the lake example of all time. Air, Water and land pollution cause changes to the environment. Using natural resources, even fossil fuel, changes the environment.
