All organisms need an
environment that will allow them to reproduce. Now, that can mean lots
of things. Humans for instance, need a place where they will find food,
water and sun light. They will also need shelter in order to be able to
protect their babies. But bacteria for example, they can live literally
anywhere. They live in places as acidic as our stomachs, as hot as
volcanoes, and as cold as ice in the poles.
