3. Which of the following is not an autotrophy?
- A. A. mushroomCorrect
- B. B. chlamy domonas
- C. C. zea mays
- D. D. mangifera indica
Explanation
Chlamydomonas, Zea mays & Mangifera indica are green plants. They are thus autotrophs since they can manufacture their own food. Mushroom is a fungus; it cannot manufacture its own food since it does not possess chlorophyll, so it is not an autotroph — it is a heterotroph.
