Commensalism :-the two different species that are interdependent for,e.g.. An egret or jungle crow dressing the collected debrieson the corners of cattle eye thereby getting its supper while the catlle is benefitted for the possible bacterial eye infection.

Parasitism:- various organisms like ticks,leeches stick to the skin living grazing cattle.

Mutulism:-small leguminous plants grow rootnodules thwt are the colonies of nitrogeb\n fixing bacteria and therefore fetting xtra nitrogen to be stored in seed cotyledons on the opther hand the nitrifying bacteria is getting safe place to live if such nodules are cut carefully it is observed that nodules quickly dry to die and the same creeper plants dwindles-charactic of mutulism
