Question

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

• A. Heterotrophs
• B. Autotrophs
• C. Parasites
• D. Saprophytes

Answer 1

The correct option is B

Autotrophs

The correct option is B.

Explanation for Correct option:

1. An autotroph, or main producer, is a living organism that uses carbon from simple molecules like carbon dioxide to generate complex organic compounds, usually with the help of light or inorganic chemical reactions.
   

Explanation for Incorrect option:

Option A:

1. Heterotrophs are organisms that are unable to prepare their own food from natural sources and hence rely on the food produced by other organisms (autotrophs).
2. They rely on these producers for food, whether directly or indirectly.

Option C:

1. A parasite is a parasitic organism that lives on or inside its host and feeds on or at the expense of that host.

Option D:

1. Saprotrophic nutrition, also known as lyotropic nutrition, is a chemoheterotrophic extracellular digesting process used to break down degraded organic materials.

Final answer:

A primary producer, often known as an autotroph, is an organism that generates complex organic substances
