If 10 joules of energy is available at the producer level, then amount of energy present at the level of secondary consumers is
10J
1J
0.1J
0.01J
As discussed in 10 Percent Law of Energy Flow -
10 percent law -
The number of trophic levels in the grazing food chain is restricted as the transfer of energy follows 10 percent law.
According to the 10% rule, the flow of the energy takes place as:
Producer (10J) --> Primary consumer (1J) --> Secondary consumer (0.1JJ)
Hence, the correct option is (c)
