Q9 of 67 Page 103

In relation to energy transfer in ecosystem, explain the statement "10kg of deer's meat is equivalent to 1 kg of lion's flesh".

Energy transfer in an ecosystem follows a ten percent rule which states that 10% of energy is transferred to the next trophic level. So, if the lion eats 10 kg of deer meat then only 10% energy would be passed to the lion i.e., 1 kg of lion’s flesh.
