Q5. 
As well as food, animals need somewhere to live. Some animals simply move into the best place they can find, but 
others build a home for themselves. A particularly intelligent builder is the beaver. Beavers live by rivers and 
streams and build dams to create pools of deep water which help keep their homes safe. The whole colony about 
five to six members, co-operates to create the dam with trees they’ve cut down using their long, sharp front teeth
then construct their home, which looks like a stick igloo, in side of the bank. 
Q6. 
Animals also depend on each other to keep safe. For example, they might have a signal that lets the group know 
when a threat is nearby. When an ant is crushed it releases a scent called ‘alarm pheromone’ that signals the other 
ants to come to the crushed ant and attack the enemy. Larger animals may challenge an opponent using sounds and 
body language. Wolves, for example, will growl at anything that is threatening their pack, and get ready to attack. 
They also warn each other of danger by barking. Because their pack is so important to their survival, wolves will 
even risk their lives to defend it. 
Q7. 
By living and working in groups, animals increase their chances of surviving in the wild. Each individual in the 
group contributes something that helps the others. This could be as simple as communicating where food is. Or it 
could be as difficult and dangerous as risking one’s life to protect another member of the group. By studying a 
variety of animal group one thing is for sure: teamwork works!
