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 answer is option “c”. see it was boiling water, she poured first into container “a” so it will be having the highest temperature than she poured to container b than to c and finally to container d so during this experiment the boiling water goes to lowest temperature and the last container was container d . So container a will be having the highest temperature and container d will be having the lowest temperature.
