Animals communicate with one another in many interesting ways. These may consist of signs, gestures, looks, sounds, smells or even light produced by the body.
Song and dance are the other means of communication. When faced with danger, animals warn others using signals such as mock charges, grimaces or sound.
They also call their mates, inform other members of the group about the source of food, advertise territory and 'teach' the young the ways of the world. Baby birds call their parents for help and attention and demand food. Far from being a silent world, the ocean is a noisy place.
Fishes, molluscs, sea lions, walruses, whales and dolphins chatter away in the waters using a variety of sounds-whistles, squeaks, clicks and groans which range from low pitch to ultrasonic sounds beyond the range of human hearing. Whales and dolphins are sometimes called the 'musicians of the sea' as birds are of the sky.
Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Both statements are incorrect, so the answer is both Statement I and Statement II are incorrect.
The passage names whales and dolphins, not sharks and crocodiles, as the musicians of the sea.
So Statement I is wrong about which animals are the sea's musicians.
The passage says baby birds call their parents for help and attention and demand food.
This shows baby birds can clearly express their needs.
So Statement II is also wrong, making both incorrect.
