Answer: C) 10%.
Explanation:
- The cow will get only 10% energy from the hay as the transfer of energy from a lower to a higher trophic level follows the ten percent law.
- According to the ten percent law of energy transfer, only 10 percent of the total energy gets transferred to the next trophic level in a food chain.
- For example, if the hay had 100 joules of energy, the cow will get only 10% of 100 J i.e 10 J energy.
- The reason why only ten percent energy is transferred is because the rest is lost in the form of heat in the atmosphere.
