Photoautotrophs Question 47 options: A) include only the green plants. B) eat other organisms that use light energy to make food molecules. C) make sugar by using organic raw materials. D) produce organic molecules from inorganic molecules.

D) produce organic molecules from inorganic molecules.

Explanation:

Photoautotrophs are organisms that utilize light energy from sunlight to produce their own food from inorganic substances such carbon dioxide. There major source of carbon is carbon dioxide. They can't survive in dark environment because they require light to grow.

The process by which photoautotrophs use energy derived from sunlight, water and carbon dioxide to produce organic molecules like glucose, is called photosynthesis. The organic molecules are used to carry out cellular functions such as respiration.

An example of photoautotrophs are green plants.
