A certain savanna grasshopper changes colour from green during the rainy season to brown during the dry season and black after dry season bush fires. The reason for these colour changes is that the
A.
grasshopper is getting older
B.
environmental temperature is changing
C.
grasshopper is avoiding predation
D.
grasshopper is frequently moulting
Correct Answer: Option C
Explanation
Savanna grasshoppers change color to camouflage themselves from predators and to match their surroundings:
Rainy season: Grasshoppers are green in the middle of the rainy season when vegetation is lush.
Dry season: Grasshoppers are brown in the dry season when vegetation is dry.
After a fire: Grasshoppers quickly evolve darker colors to match the altered habitat after a fire. These darker colors disappear as the landscape recovers.
