Energy transfer is unidirectional. Therefore, we need continuous supply of solar energy. Plants can utilize only < 0.1% of solar energy while animals can utilize 10% of energy obtained from plants to make their own cells and tissues. The remaining 90% is lost through respiration and metabolism. Energy transfer
