Population Growth & Carrying Capacity

What term describes the total number of individuals of a specific species existing in a given area?

• Population density

• Carrying capacity

• Population size

• Limiting factor

What is the maximum population size that an environment can sustain?

• The total number of individuals in a species.

• The number of individuals per unit area.

• The maximum population size an environment can support.

• The factors that prevent population growth.

What prevents an organism's population size from growing indefinitely?

• Carrying capacity

• Population density

• Population size

• Limiting factors

Which of the following factors is considered density-dependent for a population?

• Wildfire

• Drought

• Disease

• Hurricane

Which factor affects a population's growth regardless of its size?

• Amount of available food

• Amount of available mates

• Pollution

• Amount of available shelter

What type of population growth occurs when there are no limiting factors, causing the population to increase rapidly and indefinitely?

• Logistic growth

• Exponential growth

• Linear growth

• Stable growth

What does an S-curve typically represent in population dynamics?

• A population experiencing unlimited growth.

• A population that has exceeded its carrying capacity and is declining.

• A population whose growth slows and stabilizes around its carrying capacity.

• A population that is decreasing due to density-independent factors.
