In an ecosystem, the least efficient energy transfer link is from the
A secondary consumers to decomposers
B sun to producers
C primary consumers to secondary consumers
D producer to primary consumers
Answer is A
From the food chain, the energy flows from the producers to the primary consumer to the secondary consumers and about 90% of the energy is lost in the process of this transfer. Hence, the energy level by the time it gets to the secondary consumers, there is less energy transferred to the decomposers.
