An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment.

# data[].attributes.body
The structure of an ecosystem can be split into two main components, namely:

Biotic Components

Abiotic Components

The functions of the ecosystem are as follows:

1. It regulates the essential ecological processes, supports life systems and renders stability.

2. It is also responsible for the cycling of nutrients between biotic and abiotic components.

3. It maintains a balance among the various trophic levels in the ecosystem.

4. It cycles the minerals through the biosphere.

5. The abiotic components help in the synthesis of organic components that involve the exchange of energy.

2. Types of ecosystems

Terrestrial Ecosystem

Aquatic Ecosystem

"There lies a glassy oblong pool,
Where light and shade pursue their course.
How can it be so clear and cool?
For water fresh comes from its source."

天光云影共徘徊。
问渠哪得清如许？
为有源头活水来。”
