Define the following terms and give one example for each:
(a) Commensalism
(b) Parasitism
(c) Camouflage
(d) Mutualism
(e) Interspecific competition

Solution
(a) Commensalism is the interaction of two species in which one species is benefited while the other species is neither benefited nor harmed. For example - An orchid growing on a mango tree.

(b) Parasitism is the interaction of two species in which one species (parasite) is benefited while the other species (host) is harmed. For example -Human Liver fluke (parasite) in snails and fish (host species).

(c) Camouflage is the adaptation in which the organism is crytically coloured to merge into the surroundings and avoid being detected by the predators. For example Praying mantis which camouflages itself to look like a plant stem.

(d) Mutualism is the interaction in which both the  species are benefited. For example - Lichen is a mutual interaction between an algae and a fungus.

(e) Interspecific competition is the competition between two different species that occupy the same geographical area, for the same resources. In this interaction both the species are harmed. For example - Flamingoes and resident fishes in some shallow South American lakes.
