Study the following statements regarding food chains and select the correct ones. (i) Removal of 80% tigers from an area resulted in greatly increased growth of vegetation. (ii) Removal of most of the carnivores resulted in an increased population of deers. (iii) The lenght of food chains is generally limited to 3-4 trophic levels due to energy loss.

Assertion: The loss of biologically useful energy as heat with every energy transfer in a food chain is a consequence of the second law of thermodynamics. Reason: Energy does not remain trapped permanetly in any organism. It is either passed on to higher trophic level or becomes available to detritivores and decomposers after the organism dies.
