An aquatic food chain comprises the organisms like tadpoles, weeds, fish and water beetles. The organism which gets the minimum energy through this food chain is :
(a) water beetles (b) tadpoles (c) weeds (d) fish
The food chain of the given four organisms given is as follows:
weeds→ tadpole→ waterbeetle→ fish
According to the 10 per cent law, the transfer of energy from one trophic level to another is 10 per cent. Therefore, according to the given food chain, fishes will get the minimum energy.
