Understand the terms: Population, Community, Habitat and Ecosystem

An Ecosystem is a Community of Organisms in a particular Habitat. The Community is made up of different populations of the different species interacting within that habitat.

- Habitat includes all the "Abiotic" factors (non biological factors)
eg. cycle of daylight with dark, temperature (local or seasonal), rainfall, humidity, geology (slope of the land)

- Community of Organisms is made up of populations of different species and they are all interacting.
Population is the number of individuals of a particular species.
And species are organisms that reproduce to give fertile offspring.
