Population: Several organisms of a species together in a group that live in a specific, restricted area

Community: All the differents populations in the same habitat

Ecosystem: All the living organisms (biotic factors) and all the abiotic factors like wind, temperature in a habitat.

The ecosystem contains of

Biotic Factors Abiotic Factors
 * All living organisms
 * Not living organisms

A food chains is a series of organisms that eat one another so that energy and nutrients flow from one to the next. In a food chain, there is a linear sequence of organisms through which nutrients and energy passes when one organism eat another. Food chains intertwine into a food web since organisms normally eat or get eaten by several organisms. Food web are several food chains interwine and linked together.
