In ecology, an ecosystem is a naturally occurring group of organisms (plant, animal, and other living organisms, better
known as biotic community) living together within their environment and functioning as a unit of some sorts. In simple terms it can be defined as any condition where there is an interaction between organisms and their environment.

The word ecosystem first came into use in the 1935 by a British ecologist describing the physical and biological components of an environment considered in relation to each other as a unit.

The ecosystem composes of two main units:

  1. The entirety of life known as bicoenosis; and
  2. The medium that life exists in, know as biotope.

An ecosystem is a self-motivated and multifaceted whole where there is interaction in an ecological unit. It is better understand by saying that every species within the ecosystem are connected in some way and are dependent upon each other in the food chain. These include the exchange in energy and matter in between themselves and within the environment they live in. There must be a structured functional unit where equilibrium is achieved.

Ecosystem comes in various sizes. It can range from an entire forest to a small pond. Each ecosystem are different and are often separated by geographical
barriers by things such as deserts, mountains, oceans, or are isolated otherwise, by lakes or rivers. Many believe that these borders are never rigid and that ecosystems tend to blend into each other. Hence, the whole earth is seen as a single ecosystem, or a lake or river can be separated into several ecosystems. It all depends on the use of scale.

In an ecosystem, organisms are generally well balanced with one another and within the environment they live in. Where there are introduction of new environmental factors or new species it can create disastrous results. It can lead to collapse of an ecosystem or even death of many of its native species.

When studying the ecosystem there are several questions that are commonly asked:

  • In an arid area, how are colonization carried out?
  • If there were dynamics and changes what are they in an ecosystem?
  • At a local, regional, and global scale where it is at a current stable state, how does an ecosystem interact?
  • Is there any value in an ecosystem? If there is value, how does it interact with the ecological systems and provide benefit to humans, especially the condition of healthy water?

There can be many different studies in ecosystem. Here are some common ones:
