Lesson 5: Limiting Factors and Carrying Capacity
1. Words of the day
Limiting factor: Abiotic and biotic factors that stop a population from growing. Example: Not enough Food.
Carrying capacity: The maximum number of individuals that an area of land can support.
Sustained: To keep or keep going

4. Big Idea
An ecosystem can only keep or sustain a certain level of population. This is called carrying capacity. If the population goes above the carrying capacity the environment would be degraded and the population would go down until the resources return. Once the resources return then the population will go back up. Populations in a stable ecosystem will continually go up and down, the carrying capacity is found in the middle of this up and down pattern.
The carrying capacity is determined by many limiting factors, both abiotic and biotic. Limiting factors can include: number of predators, amount of rain, temperature, amount of food, and disease.
