Resource Partitioning – species coexist by using only part of the available resources Ex: some birds eat the same insects, but hunt for them in different placesCOMPETITION: COMPETITION Resource Partitioning : species coexist by using only part of the available resourcesPREDATION: PREDATIONPREDATION: PREDATION When one organism feeds on another Predator obtains food item via Prey This is a predator-prey interactionPREDATOR PREY INTERACTIONS: PREDATOR PREY INTERACTIONSSYMBIOSIS: SYMBIOSISSYMBIOSIS: SYMBIOSIS Symbiosis is when organisms are dependent on each other for survival One organism always benefits from the arrangement Types of Symbiosis Parasitism Mutualism CommensalismPARASITISM: PARASITISMPARASITISM: PARASITISM When one directly lives off of another organism Host provides the parasite with required resources (food, shelter, etc.) Sometimes a host may survive, many parasites can be fatal.PARASITISM: PARASITISMParasitism Human Worms: Parasitism Human WormsPARASITISM: PARASITISMPARASITISM: PARASITISM There are 2 different types of parasites: Ectoparasites External parasites – live on the outside of the host Ex: ticks, fleas, mosquitoes Endoparasites Internal parasites – live inside the host’s body Ex: bacteria, protists , tapewormsPARASITISM: PARASITISMMUTUALISM: MUTUALISMMUTUALISM: MUTUALISM Two organisms interacting for a mutual benefit They exist in a symbiotic relationship Interaction is good for BOTH species The symbiotic relationship is beneficial to both species, in ensuring their survivalMUTUALISM: MUTUALISM Red-billed Oxpeckers Ride on the backs of larger animals (buffalo, giraffes, etc.) Eat parasites (ticks) from these larger animals, which could infect the animal with disease Benefit = Oxpecker (food) & Larger Animal (loss of parasite)MUTUALISM: MUTUALISMCOMMENSALISM : COMMENSALISMCOMMENSALISM: COMMENSALISM One species survives off another species, without causing harm One species derives a benefit from interaction The other species is not harmed or does not benefit from the relationship Example – In rainforest, certain vines benefit by growing on trees which do not benefit or get harmed You do not have the permission to view this presentation.
