ECOLOGICAL NICHE~ the sum total of an organisms use of biotic and abiotic resources in its environment; its ecological roleChthamalus sp.Semibalanus sp. Habitat- is an area where an organism lives. AP Biology4

Interspecific interactions Community interactionsparasitism (-/+)commensalism (+/0)barnacles attached to whalemutualism (+/+)Water buffalo and EgretAP Biology5ParasitismIn a parasitic relationship, one organism benefits (parasite) while the other organism is harmed (host)Examples-fleas, ticks, tapeworm, mosquito

AP BiologyCommensalismIn commensalism, one organism benefits, while the other is not affectedExamples spanish moss growing on trees, or barnacles growing on whalescommensalism example

AP BiologyMutualismIn a mutualistic relationship, BOTH organisms benefitExamples lichen (algae and fungus), pollinators (insects, bats, birds, etc)Mutualism video

AP BiologySymbiotic InteractionsSymbiosis is a close ecological relationship between the individuals of two (or more) different species.Types of SymbiosisDescriptionCommensalismRelationship in which one organism benefits, but the other in neither helped nor harmedParasitismRelationship in which one organism benefits and the other is harmed in some wayMutualismRelationship in which both organisms benefitAP Biology
