The caretaker of a farm feeds hay to the cows to procure milk from them. How much energy will the cows get from the hay?
nikitadnepr [17]

<u>Answer</u>: C) 10%.

<u>Explanation</u>:

  • 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.
