Populations and Population Growth Flashcard

Front

What is a population's carrying capacity?

Back

The maximum number of individuals in a population that the available resources can support before growth is halted.

Back

Factors that limit the size of a population and depend on the population's size.

What type of population growth is characterized by a constant doubling of the population size?

Back

Exponential Growth.

Front

How would you describe logistic growth?

Back

Population growth that is initially rapid but begins to slow down as the population approaches its carrying capacity (K).

Front

What is the difference between K-selected and R-selected species?

Back

K-selected species invest more in fewer offspring and have stable populations, while R-selected species produce many offspring with less investment.

Front

What is the significance of the carrying capacity in population dynamics?

Back

It determines the maximum population size that an environment can sustain, influencing growth patterns.

Front

What happens to a population when it exceeds its carrying capacity?

Back

The population may experience a decline due to resource depletion and increased competition.

What is exponential growth?

Back

A growth pattern where the population size increases rapidly in proportion to the current size.
