When the herd of elephant reaches the jungle, the members of the herd start spreading out as each member wanted to eat its favourite leaves and twigs. After they eat ,the herd moves towards the river.

The elephants live in families that are called herds. These herds normally include adult female elephants and their offspring who are connected to each other. They help each other find resources and in taking care of the offspring. The elder female elephants help the young mothers in teaching their offspring.

The cat is happier than the horse, the bear or the monkey because cats are well treated by the human beings as compared to other animals like horse bear, and monkey.

The methods used by the elephant to keep its body cool are-
• Sprinkling water on their body by their trunk.
• Flapping of its ears serves as a heat radiators and helps then to stay cool and lose the body fats

Cruelty done to animals is called animal abuse.
• Animals like horses, monkeys, bears, tigers, lions, elephants, dogs, snakes etc are ill-treated by human being for their entertainment.

Elephants are useful to man as-
• They help in balancing natural ecosystems.
• They crush forests and dense grasslands and help the smaller species to co-exist.
• Elephants also create water holes used by other wildlife as they dig dry riverbeds when rainfall is low. They also use their tusks to help dig for water.

Living in groups helps the animals to hunt down large prey for food. It plays an important role in their evolution over a period of time. All animals live in groups as they are raised in them and later breed with their partners. Living in herds also leads to the animals to learn sharing their kill rather than competing with their companions. Animals in herds usually move around together, searching for food. Thus animals form groups for survival, they can help each other raise the young, hunt, keep watch, gather food, find shelter, and survive. Animals in groups have more eyes looking for predators or prey. They also have less work to do individually because they can share the workload.

Friends bring happiness into our lives than almost anything else. Friendships have a huge impact on your mental health and happiness. Good friends reduce stress, provide comfort and joy, and prevent loneliness and isolation. Developing close friendships can also have a powerful impact on your physical health. That is why we like to stay with your friends in groups.

Elephants help each other when in trouble. They come together to care for and rescue their young ones. Elephants are considered concerned animals. They help baby elephants who are stuck in mud holes by using their trunks to lift other elephants that are injured or dying, and even comfort upset individual elephants with a gentle touch of their trunk. Thus showing their love, care and concern for each other.
