Presentation transcript:

Carrying Capacity

The maximum number of organisms that an ecosystem can support. Limiting factors, such as food, water, and space, keep a population from growing too much. Carrying Capacity

Data Chart Quantity of Food (chips) at the Beginning Quantity of Food (chips) Collected Did you Survive? (less than 15 chips dies) (Yes/No) 50 70 100 30 Data Chart Note: You may only pick up chips with one hand.

Carrying Capacity Questions What biotic and abiotic factors might affect the survival of an organism? How does this simulation a good model for carrying capacity? In what ways is this simulation not a good model for the real carrying capacity of an environment? Carrying Capacity Questions
