Logistic growth has 3 phases. In Phase 1, the population grows rapidly. In Phase 2, population grows slowly. In Phase 3, growth stops. What causes growth to stop in the 3rd phase of logistic growth?

• Emigration
• Immigration
• Exponential Growth
• Carrying Capacity

NGSS.MS-LS2-4

What is happening at the 'A' on the graph?

• the population overshoots above the carrying capacity

• the population stops growing

• growth begins to slow down due to limited resources

• growth is speeding up due to an abundance of resources

The carrying capacity of an environment for a particular species at a particular time is determined by the

• number of individuals in the species.
• distribution of the population.
• reproductive potential of the species.
• supply of the most limited resources

A population is...

• A group of one species in one area
• Multiple species that live in one area
• All of the living and nonliving things in an area
• None of these
