Predation
|
Characteristics exhibited by predators & prey
|
|
|
Competition
|
-Must involve atleast 2 organisms
-Interspecific (between 2 different species) -Intraspecific (between the same species) |
|
|
Principle of Competitve Exclusion
|
-Interspecific competition only
-2 outcomes 1) species A will win and species B will dies 2) species A will win and species B will relocate -1 species will always survive |
|
|
Symbiosis
|
Intimate living together of 2 species
|
|
|
3 types of Symbiosis
|
-Parasitism (symbiot benefits/host is harmed)
