What is an ecosystem and what does it consist of?

An ecosystem is a large community of living organisms (plants, animals and microbes) in a particular area. The living and physical components are linked together through nutrient cycles and energy flows. Ecosystems are of any size, but usually they are in particular place.

There are many examples of ecosystems -- a pond, a forest, an estuary, a grassland.
