Show Answer
Correct Answer: C [Energy]

The correct answer is Energy. In a food chain, the transfer of energy is characteristically inefficient – a phenomenon known as the 10% rule, implying that only around 10% of the energy at each trophic level is available for transfer to the next. This invariably leads to a decrease in energy across each level of the food chain. Incidentally, due to this inefficiency of energy transfer, the length of food chains is often restricted, and extensive systems for recycling nutrients and materials exist in ecosystems.
