Solution
The correct option is D
Predation is an interaction in which one organism, the predator kills and consumes the prey. Predation and prey often have adaptation by natural selection that are related to their interaction, which helps them perform better in their role. Prey species have defense adaptations that help them escape predation.These defense may be mechanical, chemical, physical or behavioural.
Mechanical defenses such as presence of thorns or hard shells on turtles.
Chemical defenses such as poisonous chemicals produced by many animals which are extremely toxic when eaten.
Many species use their body shape and coloration to avoid being detected by predators. Animals adopt the colour of recent environments which make it very hard for the predators to identify the prey. Avoiding detection with blending in with the background and change in colour to match surrounding are the examples of camouflage
(a) is a frog blending with the background, (b) is a leaf insect that blends with the leaf and (c) is a peacock katydid insect which resembles a diseased or dead leaf,all these three are the forms of camouflage.
Option (d) is a mechanical means of defense against predation,they draw their head and limbs into the shell and eventually escape predators attack.
