Final answer:
The carrying capacity of a population is determined by density-dependent factors, which include competition for resources, predation, disease, and availability of habitat. Understanding carrying capacity helps us understand the limits of the Earth's resources and the impact of human activities on the environment.
Step-by-step explanation:
Carrying capacity refers to the maximum population size that can be supported in a particular area without destroying the habitat. It is important when discussing human population growth because it helps us understand the limits of the Earth's resources and the impact of human activities on the environment.
The carrying capacity of a population is determined by density-dependent factors. These factors include competition for resources, predation, disease, and availability of habitat. As the population size nears the carrying capacity, these factors become more pronounced and limit further population growth.
