Individuals how do plants or animals regulate their internal water balance. Population: a group of individuals of a single species inhabiting a specific area: often when you see a species you k(cid:374)o(cid:449) that it"s a spe(cid:272)ies, (cid:271)ut it"s (cid:374)ot (cid:374)e(cid:272)essarily always a clear cut thing. Morphological gross observation; commonly used by taxonomists.

A population is a distinct group of like individuals. Separated in that they have their own separate rates of birth, death, immigration, emigration: genetic disjunction disjunction. So basically you have spatial disjunction, which will give you demographic disjunction, and over ti(cid:373)e you"ll get ge(cid:374)eti(cid:272) If spatially separate during mating, will be demographically separate, and also genetically separate.
