Question
Give scientific reason : The organisms possessing chlorophyll are autotrophs.
✓
Answer
The organisms, possessing chlorophyll, can trap and utilize the solar energy to synthesize their own food using $CO_2$ and water.
This process of trapping the solar energy for synthesis of ones own food is called photosynthesis and the mode of nutrition of such organisms is called autotrophic.
In photosynthesis, the food synthesized is the simplest hexose sugar-glucose, which is utilized for obtaining energy.
The surplus glucose is stored as reserve food in the form of starch.
Hence, the organisms possessing chlorophyll are autotrophs.
