|
|
|
3 types of symbiosis
|
Parasitism, mutualism, commensalism
|
|
|
Two species competing for the same limiting resources cannot coexist =
|
Competitive Exclusion Principle
|
|
|
The dividing of scarce resources in order that species with similar requirements can use the resources in different ways, in different places, and at different times.
|
Resource Partitioning
|
|
|
Example of Resource Partitioning
|
Lizzards that live in carribean trees--they still eat the same thing but different species live in different parts of the tree so don’t compete for food.
