What do plants and photosynthetic bacteria do with radiant energy from the sun?

Options

  1. AStore it for later use
  2. BRelease it into the atmosphere
  3. CFix it to make food from inorganic materials
  4. DConvert it into heat

Correct answer

C. Fix it to make food from inorganic materials

Step-by-step solution

. Except for the deep sea hydro-thermal ecosystem, sun is the only source of energy for all ecosystems on Earth. Of the incident solar radiation less than 50 per cent of it is photosynthetically active radiation (PAR ). We know that plants and photosynthetic bacteria (autotrophs), fix Sun’s radiant energy to make food from simple inorganic materials. Plants capture only 2-10 per cent of the PAR and this small amount of energy sustains the entire living world. So, it is very important to know how the solar energy ca
