An ecosystem can be visualised as a functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment. Ecosystem varies greatly in size from a small pond to a large forest or a sea. Many ecologists regard the entire biosphere as a global ecosystem, as a composite of all
An ecosystem consists of an assembly of mutually interacting organisms and their environment in which materials are interchanged in a largely cyclical manner. An ecosystem has physical, chemical, and biological components along with energy sources and pathways of energy and materials interchange.
interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interaction between organisms and their environment. The term “Ecosystem” was first coined by A.G.Tansley, an English botanist, in 1935. Read on to explore the structure, components, types and functions of the ecosystem in the
3.1 CONCEPT OF AN ECOSYSTEM. An ‘Ecosystem’ is a region with a specific and recognizable landscape form such as forest, grassland, desert, wetland or coastal area. The nature of the ecosystem is based on its geo-graphical features such as hills, mountains, plains, rivers, lakes, coastal areas or islands.
Feb 12, 2008 · In the subject of ecology, the term ecosystem refers to the environment of life. It is a self-sustaining, structural and functional unit of biosphere. An ecosystem may be natural or artificial...
The ecosystem is the major structural and functional unit of ecology. The structure of an ecosystem is related to its species diversity; the more complex ecosystems have high species diversity. The function of ecosystem is related to energy flow and material cycling through and within the system.
“Eco-system is defined as a self regulating group of biotic communities of species interacting with their non living environment exchanging energy and matter.” Study of ecosystems is called as Ecology or the study of organisms in their natural home interacting with their surroundings is called Ecology. STRUCTURE OF ECO-SYSTEM.
An ecosystem is, therefore, defined as a natural functional ecological unit com•prising of living organisms (biotic community) and their non-living (abiotic or physio chemical) environment that interact to form a stable self-supporting sys•tem. A pond, lake, desert, grassland, meadow, forest etc. are common examples of ecosystems.
All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem. Thus, an ecosystem consists of biotic components comprising living organisms and abiotic components comprising physical factors like temperature, rainfall, wind, soil and minerals.
An Ecosystem can simply be defined as a system comprising all living organisms existing with one another in a unit of space interacting with abiotic components. Download below details about the ecosystem in PDF format.
