What would happen if no kites (birds) are left in a particular region? Which living things would increase in number? Which would decrease?
उत्तर
A kite is a predatory bird. They kill the smaller rodents and birds. They also eat dead and decaying matter. If kites are not present in nature, then these smaller rodents like animals will increase in their numbers. Kite is a top predator and hence it is not food for others. Thus, even if the kite's number falls, there will be little difference in any other animals' population.
