What amount of energy will be available to the organisms of the 2nd trophic level of a food chain, if the energy available at the first trophic level is 10,000 joules?

According to Lindeman's 10% law of energy transfer in a food chain, only about 10% of the energy available at one trophic level is transferred to the next trophic level. The rest is lost as heat during metabolic processes or remains unconsumed. Therefore, if 10,000 joules of energy are available at the first trophic level, approximately 10% of this energy will be available at the second trophic level. This translates to:

10,000 joules * 0.10 = 1000 joules

Approximately 1000 joules of energy will be available to the organisms at the second trophic level.
