<h2>Explanation:</h2>
Only a little amount of energy as 10% is transferred to the next trophic level. This is called 10% rule. So, in this case as the energy available at the secondary trophic level is 50 kilocalories and 10% of it is transferred into the tertiary level so it would be 5 kilocalories.
