An ecosystem is a system formed by the interactions of a variety of individual organisms with each other and with their physical environment. Ecosystems are nearly self-contained so that the exchange of nutrients within the system is much greater than exchange with other system.
An ecosystem, thus, is not entirely a biological entity. Any complete description of an ecosystem must include the physical environment as well as the biological components and the interactions between the two. An ecosystem is not entirely a biological entity.
The biological or biotic components of an ecosystem include both living organisms and products of these organisms. Thus microbes, all categories of plants and animals as well as their waste products are included in the ecosystems.
The non-biological or abiotic components include climatic and edaphic features, in particular climatic components like sunlight, temperature, air and water supply along with soil component such as soil nutrients which are very important contributing factors of ecosystem operation.
The biotic components are broadly categorized as producers, and consumers of different classes viz. In addition there are decomposer classes, which include mostly saprophytic organisms that help in nutrients and element recycling process. They are heterotrophic organisms that feed solely on dead organic matter, i.
The bulk of the saprophytic decomposition is carried out by bacteria, fungi and protozoans. Imagine that a piece of organic Utter falls to the floor of a forest. In a typical sequence, microscopic bacteria or fungi will excrete chemicals, called enzymes, that break down the complex chemical compounds in the object Some of the breakdown products are absorbed as food, whereas others are left behind.
These serve as a food supply for other organisms that carry the decomposition one step further. Eventually the waste products of the final line of decomposers are energy-poor mineral nutrients that are reabsorbed, and thus recycled, by plants — Fig.
During the process of production and consumption, energy is passed along, or flows, from one organism to another. For example, solar energy is converted to chemical energy within the leaves of green plants.Essay # 1.

Ecosystems are nearly self-contained so that the exchange of nutrients within the system is .
According to other definition-an ecosystem is a self-regulating group of biotic communities of species interacting with one another and with their non-living environment exchanging energy and matter.
Now ecology is often defined as “the study of ecosystems”. Ecology; Ecology addresses the full scale of life, from tiny bacteria to processes that span the entire planet. Ecologists study many diverse and complex relations among species, such as predation and leslutinsduphoenix.com diversity of life is organized into different habitats, from terrestrial (middle) to aquatic ecosystems.
Ecosystem definition: An ecosystem is all the plants and animals that live in a particular area together with | Meaning, pronunciation, translations and examples Meaning, pronunciation, translations and examples.
