Correct answer
B. The death of the organism is the beginning of the grazing food chain.
Step-by-step solution
All animals depends on plants (directly or indirectly) for their food needs, they are hence called consumers and also heterotrophs. Animals that depends on the primary carnivores for food are labeled as tertiary consumers. The energy trapped by the producer is passed on to the consumer or the organism dies, death of the organism is the beginning of detritus food chain.
