• A. Obligate mixotrophy
• B. Obligate autotrophic
• C. Facultative autotrophy
• D. None of the above

Answer 1

An organism which uses different modes for energy and carbon are known as mixotrophic organisms. It is a type of lifestyle where the organism use both autotrophic and heterotrophic modes for the survival.
