Carrying capacity can be changed by nature or humans. Which statement is true?

• A. It can be changed only by natural factors
• B. It can be changed only by human factors
• C. It can be changed by nature or humans
• D. It never changes

Answer: (C)

Carrying capacity is the number of individuals an environment can support over the long term based on available resources and habitat. It isn’t a fixed number; it changes when resource levels or habitat quality change. Natural factors can alter carrying capacity, such as drought reducing vegetation and water, climate shifts affecting food supplies, wildfires, diseases, or natural population fluctuations of predators and prey. Human factors can also change it, through habitat loss or fragmentation from development, pollution, introduction or removal of species, changes in land use, and management actions like conservation programs or predator control. So the true statement is that carrying capacity can be changed by nature or humans. It isn’t limited to just natural factors, and it isn’t fixed forever.
