Aarush , there will be not enough plants to feed so many water insects . So, at a particular time all plants will finish . So , there will be nothing left for the water insects so they will also die !

Ans 4:

Manjeet Prajapati from Saint Xavier College BHEL Jhansi , Jhansi
Class : Class 4
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.
