Solution
The correct option is C Energy
Nitrogen, oxygen, carbon, phosphorous, sulfur are essential elements which are recycled in the ecosystem by biogeochemical cycles. They pass from producer to consumer to decomposer to back to the environment. Similarly, water is also recycled in the ecosystem by water cycle. However, energy is not recycled in the ecosystem. From one trophic level to another trophic level, only 10% of the energy is transferred. The rest, that is 90% of energy is lost or utilized during this process.Thus, the correct answer is 'Energy.'
