Organisms and Populations — BIOLOGY STD 12 Science — Question

Prey species show following defence mechanisms:

1. Showing camouflage for concealment.
2. Moving at faster speed for escape.
3. Cryptic colouration to avoid the detection. This is seen in some insects. Also predators display such cryptic colouration to avoid detection. E.g. Colouration in frog.
4. Bad taste due to accumulated chemicals.
   E.g. The Monarch butterfly is highly distasteful to its predator bird as it stores a special chemical in the body during its caterpillar stage by feeding on a poisonous weed.
