Autotrophic organisms can exist in an exclusively ________________ environment?
Correct answer: B. Inorganic
- A. Organic
- B. Inorganic
- C. Wet
- D. Terrestrial
Explanation
Autotrophs use inorganic raw materials such as carbon dioxide, water and mineral salts to manufacture organic food, usually using light or chemical energy. Therefore they can exist in an exclusively inorganic environment, although they still require suitable physical conditions. Students may choose wet because many autotrophs need water, but water alone does not describe their nutritional source.
