A population is...

• A group of one species in one area
• Multiple species that live in one area
• All of the living and nonliving things in an area
• None of these

The carrying capacity of an environment for a particular species at a particular time is determined by the

• number of individuals in the species.
• distribution of the population.
• reproductive potential of the species.
• supply of the most limited resources
