Ecological Relationships: How living organisms interact with each other

Competition: When individuals or species “fight” for resources Plants competing for sunlight Lion and hyenas competing for a kill

Herbivory: When a consumer eats a producer s/cr15169/cr jpg A fruit bat eating a papaya A woodchuck eating wild clover

Predation: When a consumer eats a consumer. An eagle eating halibut. A lion eating zebra. content/uploads/2007/06/close-up-bald-eagle-eating.jpg

Symbiosis: Long-term relationship between two different species that live close together and at least one of the species benefits.

Type of Symbiosis: Mutualism Both organisms benefit from the relationship. WIN – WIN situation Ostriches and gazelles

Type of Symbiosis: Commensalism One organism benefits and the other is unaffected WIN – NEUTRAL situation Copyright, Ray Norton Eastern chipmunk and soil mite

Type of Symbiosis: Parasitism One organism benefits and the the other is harmed WIN – LOSE situation Department of Botany, Iowa St. University Michael Clayton, Wisconsin State Herbarium Honeysuckle is a parasite to the host dogwood tree A parasite does not want to kill its host as it would require finding another one!
