Presentation transcript:

Carrying Capacity

What would inhibit the population of rabbits from continuously growing?

Limiting Factors Any biotic or abiotic factor that restricts the existence, number, reproduction, or distribution of organisms. Examples: water, temperature, space, disease, predation

Population Growth

Exponential Growth J-shaped curve shoes exponential growth Exponential growth – as a population gets larger, it also grows at a faster rate

Why does it level off?

Carrying Capacity The number of organisms of the same species that an environment can support

What does this tell you about the relationship between hares and lynx?

Predator – Prey Relationship The number of predators and prey in a given area is dependent upon each other.
