85) (E) MIMICRY - It is an evolved mechanism in resemblance between same species or different species to protect their survival . EXPLANATION- In the two species of orange butterfly one is palatable to bird predators and the other one is not . Hence the palatable one butterfly may evolve them to resemble with non palatable butterfly to protect them from predator bird. So the rare one is palatable and the common one is non palatable .
86)(B) MUTUALISM- it is a condition in which both the organism dependent on them for their survival or for different need. EXPLANATION- It is example of ant-fungus symbiosis mutualism in which ant cultivate the fungus for food . so the fungus will grow and ant get their food both are benefited .
(87)COMPETITION- The competitive exclusion principle says that two species can not co-exist if they occupy the same niche. EXPLANATION- The resident species compete with the immigrant species for the same resource hence the competitively inferior one (immigrant spicies) eliminate.

85. Two species of orange butterflies differ in their palatability to bird preda- tors; one species is common and the other is rare. 86. Specific species of fungi grow in special chambers of certain ant nests. 87. Island immigrants usually fail to colonize successfully when their potential niche is occupied by a resident species. 88.
