... A population is the number of a particular species living in a particular area. When a species first moves into an area, e.g. a feral animal or after a big disturbance, its population will usually increase rapidly. However, a time will come when the organism will have outgrown the carrying capacity ...

Maintaining Balance

Organism specialization: 1. Habitat: The place in which an organism lives—it provides food, water, cover, and space. 2. ...

Outline
... The ecological niche is the sum total of an organism’s use of abiotic/biotic resources in the environment. An organism’s niche is its role in the environment. The competitive exclusion principle can be restated to say that two species cannot coexist in a community if their niches are identical. ...
