community ecology
Definition: study of how interactions between species affect community structure & organization

Example: A group of different species living in the same habitat.
competitive exclusion principle
Definition: principle stating that two species competing for the same limiting resource cannot coexist

Example: In our picture, the turtles and bears compete over eating berries. Due to the competitive exclusion principle, they cannot coexist indefinitely because they both need it to survive.
competitive exclusion principle
Definition: principle stating that two species competing for the same limiting resource cannot coexist

Example: two Insects that compete for food/resources in their habitat (leaf). The gold insect dies off to to the competitive exclusion principle.
resource partitioning
Definition: when two species divide a resource, based on differences in their behavior or morphology

Example: This is an example of a watering hole in the Amazon, with a lion and a zebra drinking water from the same place.

Example: A slug living on a tree. The tree isn't harmed nor helped, however, the slug is provided with a habitat.
keystone species
Definition: plays a far more important in its community than its relative abundance might suggest

Example: Otters because they are very important to kelp forests by keeping them under control
ecosystem engineer (foundation species)
Definition: a keystone species that creates or maintains habitat for other species

Example: Beaver
