Overpopulation refers to a situation where the number of organisms in a particular habitat exceeds the carrying capacity, leading to resource depletion and environmental degradation.
This is the rate at which a population increases in size if there are no density-dependent forces regulating the population. It's like tracking how quickly guests arrive at your party.
These are environmental conditions that limit the growth, abundance, or distribution of an organism or a population within an ecosystem. They're like rules set by the host (like only 50 guests allowed) that control how big the party can get.
