What are the essential components of any ecosystem?

Any ecological system requires some components. These are some environmental conditions. You need an atmosphere, a suitable temperature, the presence of sunlight, and so on. Also, inorganic chemicals are needed, which are needed for living organisms. The ecosystem requires a wide variety of living organisms. The more different species live in an ecosystem, the more stable this ecosystem. Man failed to create an artificial ecological system, although theoretically it is quite possible.
