Number of which consumers will decline and which will increase?

1.	Number of which consumers will decline and which will increase?
Answer» Solution : The food chain if altered, results in imbalance in the ecosystem. 'Paddy `to` Grasshoppers `to` Frog `to` Snake', this food chain is natural. When by any reason there is decline in the NUMBER of frogs, THUS SECONDARY CONSUMER will also decline. Due to this decline, snake which is at tertiary consumer level will also decline. The primary consumers i.e. grasshoppers will increase as there is now no check on their population. Due to increase in their population the paddy production will be reduced. Due to reduced number of snakes, rats and other RODENTS from neighbouring areas would also rise, which are also secondary consumers.
