Population Growth

Exponential population growth can be described as

• growth when resources are limited

• a j-shaped curve

• a s-shaped curve

• growth that reaches carrying capacity

Density-independent limiting factors to population growth includes

• stress from overcrowding

• parasitism

• competition

• natural disasters

What is a condition that halts population growth?

• limiting factors
