Answers
Answer:
Explanation:
By preparing a variety of foodstuffs and dishes at home, we do not become autotrophic. Autotrophic is a term that is used for organisms that can produce their own food. We humans depend on plants for our food and the products which we get from them are used by us to make a variety of foodstuffs. Also, autotrophic organisms contain chloroplast which is an absolute necessity to be classified as an autotroph and we do not possess any such structures. So, we cannot be considered autotrophs.
