Solution (By Examveda Team)

Termite is a polyphagous pest.
Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter and soil humus.
Males (drones) are haploid and develop from unfertilized eggs, while females (both workers and the queen) are diploid and develop from fertilized eggs.
Termites are polyphagous pests causing economic losses to a large number of crops worldwide.
