What is carrying capacity?
|
The largest number of individuals of a species that an environment can support and maintain for a long period of time
|
|
|
What happens if a population gets bigger than the carrying capacity?
|
The species in the population will die out or be forced to move elsewhere.
|
|
|

|
|
|
Example of parasitism.
