(A) Monarch butterfly (III) Camouflage
(B) Cuckoo bird (I) Brood parasitism
(C) Cuscuta (IV) Parasitism
(D) Sea anemone and Clown fish (II) Commensalism

Cryptic coloration is a type of camouflage that helps prey blend in with their surroundings. This makes it difficult for predators to see them, which can help them to avoid being eaten. Some species of insects and frogs are cryptically-coloured (camouflaged) to avoid being detected easily by the predator. Prey that match the color of their surroundings are more difficult to see.Some are poisonous and therefore avoided by the predators. The Monarch butterfly is highly distasteful to its predator (bird) because of a special chemical present in its body. Interestingly, the butterfly acquires this chemical during its caterpillar stage by feeding on a poisonous weed.

Brood parasitism in birds is a fascinating example of parasitism in which the parasitic bird lays its eggs in the nest of its host and lets the host incubate them.e.g. the movements of the cuckoo (koel) and the crow during the breeding season (spring to summer) and watch brood parasitism in action.

Cuscuta, a parasitic plant that is commonly found growing on hedge plants, has lost its chlorophyll and leaves in the course of evolution. It derives its nutrition from the host plant which it parasitises. It is an example of parasitism.

Commensalism: This is the interaction in which one species benefits and the other is neither harmed nor benefited. Example is the interaction between sea anemone that has stinging tentacles and the clown fish that lives among them. The fish gets protection from predators which stay away from the stinging tentacles. The anemone does not appear to derive any benefit by hosting the clown fish.
