Population- a group of potentially interbreeding individuals of a single species inhabiting a specific area. Population of plants or animals may occupy the a mountain top or a river basin. Many attributes of population are determined by interactions between the physiological ecology of a species and the biotic and abiotic conditions that individuals in a population encounter. Population ecology serves as a bridge between the physiological and community ecology. Study population because understanding to natural processes can provide insight to general processes. The distribution of a population include size and shape and location of the area it occupies. Density- the number of individuals per unit area. Absolute density- is what most scientist refer to when they say density number of individuals in a population per unit area. Ecological density- incorporates the concept of a niche in that not all of the condition found within a given area will contain the niche requirements of a particular species.
