assemblage of interacting populations of different species
community
inTERspecific
between species
INTRAspecific
within species
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.
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
___________= species live in different places.
Allopatric
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.
