Population Growth Patterns
Population growth means the increase in the number of individuals in a population. It depends on four key factors: birth rate, death rate, immigration, and emigration.
The birth rate is the number of individuals born in a population within a specific time period, while the death rate is the number of individuals who die within the same period.
Immigration occurs when individuals move into a population from another area, increasing its size, while emigration occurs when individuals leave a population, decreasing its size.
Factors like predators, diseases, and food shortages can limit population growth.
When resources like food, water, and space are unlimited, populations grow quickly. This is called exponential growth and forms a "J-shaped" curve.
But in nature, resources are limited. As a population grows, it eventually reaches an upper limit that the environment can support, known as the carrying capacity. This results in a new population growth pattern that forms an S-shaped curve called logistic growth.
