Answer 1

Organisms that prepare food for themselves using simple naturally available raw materials are referred to as autotrophs.

Explanation:

Autotrophs are those organisms that are able to prepare their own food by the process of photosynthesis, e.g., green plants. Photosynthesis (Gk photos - light, synthesis) is an enzyme regulated anabolic process of manufacturing organic compounds inside the chlorophyll-containing cells from carbon dioxide and water with the help of sunlight as a source of energy.
