BiologyInter-specific relationshipsCompetitionAn example of interspecific competition in a conifer forest would be pine, spruces, firs, and cedars - - all competing with one another for resources like nutrients, space, and sunlight.

Competition is a negative aspect for all species. Amazon Rain forest. Stag Bettle.GrazingGrazingis a type offeeding, in which aherbivorefeeds onplants(such asgrasses), and also on other multicellularautotrophs(such asalgae). Mountains, Sheeps

ParasitismParasitismis a non-mutualsymbioticrelationship betweenspecies, where one species, theparasite, benefits at the expense of the other, thehost.Parasitism may benefit neither of the species but the opposite one to the one benefiting will be unbenefited. Amazon Rainforest, Caterpillar and parasitic warspMutualism & CommensalismMutualismis a biological interaction between two organisms, where each individual derives a fitness benefit. An example would be a bees pollinate trees -- the bee gets food, the tree gets pollinated.Commensalismis the relation between two different kinds of organisms when one receives benefits from the other without damaging it. An example could be a flatworm attaching to the horse crab and eating the crab's food while the crab is unaffected.
