Verified step by step guidance1
Understand the concept of carrying capacity: Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely, given the available resources such as food, habitat, water, and other necessities.
Recognize the implications of reaching carrying capacity: When a population reaches its carrying capacity, the resources available are just enough to support the current population size.
Analyze the relationship between birth rates and death rates at carrying capacity: At carrying capacity, the birth rate equals the death rate, leading to a stable population size.
Consider the options given: Evaluate each statement based on the definition and implications of carrying capacity.
Identify the correct statement: The statement 'The population size remains stable as birth rates equal death rates' accurately describes a population at carrying capacity.
