Match the items in Column A with those in column B. Column A Column B 1 . Symbiosis (a)One organism depends on another organism for food, but the second organism gets no benefit. 2 . Parasite (b) Interaction between species, in which one kills and eats the other. 3 . Predation (c) Organism of two different species living together with mutual benefit.

1-(c) Symbiosis is defined as the living together of two or more organisms of different species in an intimate association in which both the partners are benefited. The symbiotic association is of two types i.e commensalism and mutualism. 2-(a) Parasitism is an interaction between two individuals, wherein the parasite gets the benefit at the expense of the host. 3-(b) Predation is an interaction between members of two species in which members of one species capture, kill, and eat up members of other species. The former are called predators while the latter is called prey.
