Environmental Relationships

Types of Relationships Predation Competition Parasitism Mutualism Commensalism

PREDATION Predation is the feeding on and typically killing another organism. Herbivory is comparable to predation, but herbivores feed on plants rather than animals.

COMPETITION Competition describes multiple organisms fighting for the same resources.

INTERSPECIES COMPETITION Competition between different species.
