Biological population growth
WebHumans are unique in their ability to alter their environment with the conscious purpose of increasing its carrying capacity. This ability is a major factor responsible for human population growth and a way of overcoming density-dependent growth regulation. Much of this ability is related to human intelligence, society, and communication. WebTerm. Meaning. Population. A group of individuals that belong in the same species and live in the same area; for example, the stray cats of New York City. Population ecology.
