In the given food chain, tadpole feeds on water insect and in turn is eaten by small fish. If population of tadpole will decline with time then small fish population will also decrease as former is the food of later. On the other hand, water insect population will be positively affected because in the absence of predator prey population reproduces and flourishes.

The correct answer is C because if organism X wipes out all tadpoles in the community, then water insects' population grows with nothing to eat them. The small fish die because they have nothing to eat, and soon the big fish die too.

Sorry ,answer is A .I gave wrong explanation why .You have told arerespectively, so gas 1 is carbon dioxide and gas 2 is oxygen.You have given the order as 1 and 2 i.e. carbon dioxide and oxygen.So ,we will say it as 2 and 1 i.e oxygen and carbon dioxide .Hence answer is A.
