How is an autotroph different from a chemotroph?

Answer 1

An autotroph uses co2 as primary carbon source where as chemotroph uses chemicals as primary energy source. Chemotrophs also require a source of organic nutrient, and autotrophs would be considered a photosynthesizer.

Answer 2

Chemotrophs are organisms that can use chemicals to create energy while autotrophs is a much broader term that includes chemotrophs. Autotrophs are defined as organisms that can generate their own energy without consuming organic material.

Answer 3

An autotroph is an organism that can produce its own food using energy from sunlight or inorganic compounds, while a chemotroph is an organism that obtains energy by breaking down chemical compounds in its environment. Autotrophs rely on photosynthesis or chemosynthesis, while chemotrophs use chemical reactions to obtain energy.
