Write a summary of the following passage within 100 words:
Communication is part of our everyday life. We greet one another, smile or frown, depending on our moods. Animals too, communicate. Just like us, interaction among animals can be both verbal and non-verbal. Singing is one way in which birds can interact with one another. Male blackbirds often use their melodious songs to catch the attention of other blackbirds. These songs are usually rich in notes, encoding various kinds of messages. Songs are also used to keep off other birds from their territory, usually a place where they dwell. Large mammals in the oceans sing too, according to adventurous sailors.
Enormous whales groan and grunt while smaller dolphins and porpoises whistle and click. These sounds are surprisingly received by other mates as far as several hundred kilometres away. Besides singing, body language also forms a large part of animals’ communication modes. Dominant hyenas exhibit their power by raising the fur hackles on their necks and shoulders, while the submissive ones normally surrender to the powerful parties by crouching their head low and curling their lips a little, revealing their teeth in a friendly smile. Insects such as wasps armed with poisonous bites or stings usually have brightly painted bodies to remind other predators of their power. (206 words)
Ans. Communication helps man to express their emotions and moods. Animals, birds and insects also communicate with themselves. Communications are of two types such as verbal and non-verbal. Birds interact with themselves through verbal expression by singing to catch the attention of others or to keep off others from their territory. Aquatic creatures send messages to their partners by groaning and grunting. Wild animals use non-verbal expressions by hackling their fur, crouching their heads, curling their lips and revealing their teeth. Few insects with their stings and colourful body warn their predators. (91 words)
