Only 10 % of energy is transferred from one trophic level to the next trophic level of a food chain (ten percent law, given by Linderman). In present case, energy available at producer level is 10 J. Hence energy at primary consumer level would be 1 H (10% of 10 J). Similarly, at secondary consumer level, energy present will be 0.1 J (100 % of 1 J).

Explanation:
In an ecosystem, energy flows from one trophic level to another through the food chain. The producer level, also known as the first trophic level, consists of autotrophic organisms such as plants that convert solar energy into chemical energy through photosynthesis.
When 10 joules of energy is available at the producer level, it means that the plants have produced 10 joules of energy through photosynthesis.
The energy available to the secondary consumer, which is at a higher trophic level, is determined by the energy transfer efficiency between trophic levels. Energy transfer efficiency refers to the amount of energy transferred from one trophic level to the next.
Energy transfer efficiency is typically low, ranging from 10% to 20%. This is because energy is lost as heat, not all parts of the organism are consumed by the next trophic level, and there are metabolic processes that require energy for maintenance and growth.
Calculation:
Let's assume an energy transfer efficiency of 10%.
Energy available to the secondary consumer = 10 joules (energy available at the producer level) * 0.10 (energy transfer efficiency)
Energy available to the secondary consumer = 1 joule
Therefore, the amount of energy present at the level of the secondary consumer is 1 joule.
Conclusion:
The correct answer is option C) 0.1 J. This means that only 0.1 joules of the initial 10 joules of energy is available at the level of the secondary consumer. The remaining energy is lost as heat or used for metabolic processes.
