Which one of the following shows a unique relationship with an insect that has coevolved with it and that is the only insect that can pollinate this tree ?
A
Fig
Correct answer
B
Mahua
C
Sandalwood
D
Silk cotton
Explanation
Fig trees and fig wasps are a classic example of coevolution and obligate mutualism. Each fig species is generally pollinated only by its own species of fig wasp, which breeds inside the fig's enclosed inflorescence (the syconium), and neither can reproduce without the other. Mahua, sandalwood and silk cotton are pollinated by a range of insects, birds or bats.
