Population Dynamics

• Competition
• Limiting Factors
• Carrying Capacity Biotic Potential

• POP

2
Competition

• Competition occurs when two or more organisms
  seek the same resource at the same time.
• Competition reduces population size.

• Competition exists for FOOD, LIVING SPACE OTHER
  RESOURCES

White-tail Deer in NH compete for plant materials
and wooded areas (habitat).
3
Limiting Factor

• Anything that restricts the number of individuals
  in a population
• availability of water, food, shelter, space
• competition, predation, disease

Limiting factors for the white-tail deer
population in NH would include loss of habitat
food sources due to human development.
4
Carrying Capacity

• Carrying Capacity is the largest number of
  individuals of one species that an ecosystem can
  support over time.

White-tail deer in NH might have moved into a
residential area because a nearby forests
carrying capacity for deer has been reached.
5
Biotic Potential

• The highest rate of reproduction under ideal
  conditions.
