Presentation Transcript

Slide1

Limiting Factors

BIOLOGYSlide2

Limiting Factors

Limiting factor:

Anything that prevents a population from growing too

large

Examples? Discuss

Space (disease, predation)

Sunlight

Competition (food, water, mates)Slide3

Why do males chase females?

Limiting factor: eggs Slide4

Density-Dependent Limiting Factors

Any factor limiting the size of a population whose effect

is dependent

on the

population size.

Examples?

Disease (overcrowding)

Competition (food, water, shelter)

PredationSlide5

Density-Independent Limiting Factors

Any factor limiting the size of a population whose effect

is NOT dependent

on the population size.

Examples?

Drought

Natural disasters

Damming rivers, clear-cutting forests Slide6

Carrying Capacity

Carrying

Capacity:

Maximum number of individuals an environment can support

After overshoot.. Population decline, then recovery Slide7

Carrying Capacity Graph Slide8

The carrying

c

apacity is limited by limiting factors!

Exponential Growth

Population decline

Recovery/stabilization Slide9

What’s Due

Engineering sketch

Materials/items (for building)
