Vedclass · Answer

(A) The living world on Earth is primarily driven by solar energy. Plants and photosynthetic bacteria capture a small fraction of the total solar radiation reaching the Earth. This specific portion of the solar spectrum,which is utilized by plants for photosynthesis,is known as $PAR$ (Photosynthetically Active Radiation). $PAR$ constitutes less than $50 \%$ of the incident solar radiation. Plants capture only $2-10 \%$ of this $PAR$ to synthesize food,which sustains the entire ecosystem.
