Population Growth

What is a J-shaped curve?

• A graphical representation of exponential growth, where the population size increases rapidly without limits.

• A linear representation of population decline over time.

• A cyclical pattern of population growth and decline.

• A bell-shaped curve representing normal distribution.

What is overpopulation?

• A situation where the number of individuals exceeds the carrying capacity of the environment, leading to resource depletion.

• A condition where the population is below the environmental capacity.

• A scenario where resources are abundant and population growth is sustainable.

• A phenomenon where the population is evenly distributed across the environment.

What is a limiting factor?

• A resource that promotes the growth of a population.

• Any resource or environmental condition that restricts the growth of a population.

• A factor that has no effect on population growth.

• A condition that only affects the reproduction of a species.

What is exponential growth?

• A period of rapid growth where the population increases at a constant rate, leading to a J-shaped curve on a graph.

• A gradual increase in population size over time, resulting in a linear growth pattern.

• A decline in population size due to limited resources and environmental factors.

• A sudden spike in population due to migration or external factors.

What role does competition play in population growth?

• Competition for resources can enhance population growth by increasing the availability of food and space.

• Competition for resources can limit population growth by reducing the availability of food, space, and other necessities.

• Competition has no effect on population growth.

• Competition leads to an increase in population size by promoting cooperation among individuals.

What is logistic growth?

• A type of population growth that starts exponentially but slows as the population reaches carrying capacity, resulting in an S-shaped curve.

• A type of growth that continues indefinitely without any limits.

• A growth pattern that decreases as resources become scarce.

• A linear growth pattern that increases at a constant rate.

What is an S-shaped curve?

• A graphical representation of exponential growth, where the population size increases indefinitely.

• A graphical representation of logistic growth, where the population size grows rapidly at first and then levels off as it approaches carrying capacity.

• A type of curve that represents linear growth over time.

• A graphical representation of cyclical growth, where the population size fluctuates regularly.

What is immigration?

• The movement of individuals into a population, which can lead to an increase in population size.

• The process of individuals leaving a population to settle in another area.

• The legal process of obtaining citizenship in a new country.

• The act of traveling to a different country for tourism purposes.

What is carrying capacity?

• The total number of species in an ecosystem.

• The maximum number of individuals of a species that an environment can sustainably support.

• The minimum number of individuals required for a species to survive.

• The average number of individuals in a population over time.

What is the predator-prey cycle?

• The dynamic relationship between predator and prey populations, where the population sizes of each influence the other.

• A fixed ratio of predators to prey that remains constant over time.

• A cycle that only occurs in aquatic ecosystems.

• A phenomenon where predators become extinct due to overhunting.
