Answer 2

the fertile plains attract more population than the plains which are not fertile. this is because in the fertile plains people will be able to grow crops and keep their animals. the crops will yield to food for the people and for the animals too. when people have food both for them and their animals, life runs smoothly for them. the crops to be grown can be either cash crop or food crop. the people may sell the cash crops and so earn a living for themselves.
