If all the snakes are killed then the population of rats will increase as there will be snakes to feed on them.also the population of wheat will reduce as there will be more rats to feed on there will be not snakes then peacock will also eat wheat only.this will further reduce the wheat population.there will also be reduction in the population of peacock as they feed on peacock on snake also.

If the snakes are vanished then,the population of peacocks shall decrease because peacocks food is snakes.due to less food their population shall decrease.and the population of rats will increase because snakes wont be anymore to eat the rats.............and when there are so many rats,the amount of wheat shall also decrease or become extinct....this will create imbalance in the food wed/chain.
