1 Review List three density dependent limiting factors

2 Review What is a density independent limiting factor

Apply Concepts Give three example of a density independent limiting factor that could severely limit the growth of a population of bats living in a cave

CH 5 POPULATIONS5.2 Limits to Growth

In its native Asia, populations of hydrilla increase in size until they reach carrying capacity, and then population growth stops. But here in the United States, hydrilla grows out of control.

Limiting Factors Thing(s) that affects

the growth of a population.

Carrying Capacities and Limiting Factors

What controls Horse populations Why

Whitetail Deer Why

Humans Why.

Density-Dependent Limiting Factors

Occur at high population densities Competition, predation, herbivory, parasitism,

disease, and stress from overcrowding.

Density-Independent Limiting Factors

Affects all populations in similar ways Unusual weather such as hurricanes, droughts, or

floods, and natural disasters such as wildfires.

True density Independence

A very cold winter and heavy snowfall.
