What is carrying capacity?

Back

The maximum number of individuals of a population that the environment can support.

Front

What factors have contributed to the dramatic increase in world population?

Back

Better medicine, better sanitation, and better technology.

Front

What are r-strategists?

Back

Organisms that typically live in unstable environments, reproduce rapidly, do not care for their young, and are subject to predation.

Front

What are k-strategists?

Back

Organisms that occupy stable environments, are larger in size, have longer life expectancies, and invest more in fewer offspring.

Front

What is the difference between r-strategists and k-strategists?

Back

R-strategists reproduce quickly in unstable environments, while k-strategists reproduce slowly in stable environments.

Front

What is exponential growth in population dynamics?

Back

A rapid increase in population size when resources are abundant, often represented by a J-shaped curve.

Front

What is logistic growth in population dynamics?

Back

A growth pattern that starts exponentially but levels off as the population reaches carrying capacity, represented by an S-shaped curve.

Front

What is a population crash?

Back

A sudden decline in the number of individuals in a population, often due to resource depletion.

Front

What is mutualism?

Back

A symbiotic relationship where both species benefit from the interaction.

Front

What is a lag phase in population growth?

Back

The initial period of slow growth in a population before it begins to increase rapidly.
