An ecosystem is a system formed by the interactions of a variety of individual organisms with each other and with their physical environment.

Functions of Ecosystem:

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. The leaves can then be eaten by some herbivore, and the herbivore may, in turn, be eaten by a carnivore.

Consider a hypothetical ecosystem that receives 1, Kilocalories of light energy in a given day Fig. Most of this energy is not absorbed at all.

Some is simply reflected back into space. Of the energy that is absorbed, most is stored as heat or used for evaporation of water. A small amount is assimilated by plants.

The productivity in an ecosystem are of two kinds—primary productivity and secondary productivity. The primary productivity of an ecosystem is the rate at which organic matter is produced during photosynthesis. Some amount of photosynthetic material is subsequently utilized for respiratory purpose.Video: Pond Ecosystem Lesson for Kids In this lesson, you'll learn about the pond ecosystem.

We will take a close look at what a pond is, what makes up a pond ecosystem and what it takes to. - Introduction An aquatic ecosystem is an ecosystem takes place in a body of water, which has a community of organisms that depend upon each other to live and function.

Three major ecosystem functions are energy flow, nutrient cycling, and biodiversity. An ecosystem can be natural or artificial, temporary or permanent, e.

g. large grassland, a forest, a village, an aquarium or a pond can all be regarded as ecosystems. The various constituent of Here is your essay on the Ecosystem.

An ecosystem is a complete community of living organisms and the nonliving materials of their surroundings. Thus, its components include plants, animals, and microorganisms; soil, rocks, and minerals; as well as surrounding water sources and the local atmosphere.

Fun Facts About Ecosystems for Kids. Animals and plants within an ecosystem depend on each other for their survival. If conditions change, the animals and plants have to adapt.
