Population

A population of Babie dolls that live in my house (and Lamby).

A population is a group of one type of species living in one geographical area. The species must be capable breeding with one another and live near each other to be defined as a population. A population undergoes three phases throughout its lifespan: growth, stability, and decline. It will both increase and decrease over time due to a change in the amount of resources or a change in neighboring populations. If the number of resources exceeds the number of organisms or an opposing population is at a decline, the population will grow. Once the population has surpassed the spare resources, it will stabilize. Eventually the population will decline when resources have become more limited or the opposing population is stronger. There are many other factors that may determine deterioration in population count such as human impact, pollution, and new species. Examples: number of gumballs in a gumball machine, number of people in the United States, and number of socks in a dryer.
