B
In nature, there are many kinds of animals, such as tigers, lions, elephants and so on. Some of them usually live alone. For example, tigers like living by themselves. But for some small animals, they also have their own ways to survive — to work together with each other.
Meerkats live in arid regions, and they have enemies everywhere. To survive, they have all the skills to live there. For example, they can see their enemies from far away. But they cannot survive alone. They survive because of one skill — they usually live and work together as a team. For them, teamwork means life or death.
Meerkats live underground in large groups and have different group roles. Some watch for enemies, some look after the young meerkats and others go out to find food. Meerkats can't talk like humans, but they can transit information by different sounds. They can tell others where the enemy is — an eagle in the air flying to them or a snake on the ground.
So what can people learn from these amazing animals? They show us the importance of teamwork.
