Ecosystem represents a relationship between organisms and their environments in a particular area at a certain time. It consists of all living organisms biotic factors and non-living, chemical and physical components abiotic factors of the environment with which the organisms interact such as air, soil, water and sunlight. The entire array of organisms inhabiting a particular ecosystem is called a community.

The term ecosystem was coined by A. Though the organisms may claim out primary interest, when we are trying to think fundamentally we cannot separate them from their special environment which they form one physical system. It is the systems so formed which…………………..

There are quite a few forest ecosystem pdfs , available for those inclined to research into this further. Real assets versus financial assets 1. The tank water first flows into a narrow chamber full of bioballs. Urban Land Institute. There are two main components of an ecosystem which are in constant communication with each other. Shankar IAS Environment Book covers all major topics of environment and ecology and the language of this easy to understand. Together with freshwater ecosystems, marine ecosystems are also part of the broader category of aquatic ecosystems.

An organism is always in the state of perfect balance with the environment. The environment literally means the surroundings. The environment refers to the things and conditions around the organisms which directly or indirectly influence the life and development of the organisms and their populations. Organisms and environment are two non-separable factors. Organisms interact with each other and also with the physical conditions that are present in their habitats. The concept of ecosystem was first put forth by A. Tansley

For this purpose, the shares of indicators as a percentage of their total number in the dynamics of negative changes in aquatic ecosystems were compared on the basis of long-term monitoring information of Roshydromet and data of own expeditionary investigation in reservoirs on hydrobiological, toxicological and physico-chemical indicators. The role of the biotic component increases as the state of the aquatic ecosystem deteriorates of the Tsimlyansky reservoir, on the contrary, decreases in the Manychsky it is established. The role of the abiotic component is great and similar in all reservoirs; it increases already in a state extraordinary ecological situation but in ecological disaster is somewhat reduced. It is concluded that the proposed new approach to the analysis of the role of biotic and abiotic components in the development of negative changes in the ecosystem opens up new opportunities in the study of the formation of water quality and the state of water bodies.

Components of Ecosystem: Biotic Components and Abiotic Components (with info-graphics)

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter , decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes. Ecosystems are controlled by external and internal factors. External factors such as climate , parent material which forms the soil and topography , control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. Ecosystems are dynamic entities—they are subject to periodic disturbances and are in the process of recovering from some past disturbance.


Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.

    The determinants of diversity are a central issue in ecology, particularly in Andean forests that are known to be a major diversity hotspot for several taxa.
