Question

Which life process is classified as autotrophic in some organisms and heterotrophic in others?

• A. Hormonal regulation
• B. Nutrition
• C. Anaerobic respiration
• D. Transport

Answer 1

The correct option is B Nutrition

Nutrition is classified as autotrophic and heterotrophic. Autotrophic organisms can synthesise their own food (e.g., green plants, blue-green algae and some bacteria). While some organisms exhibit a heterotrophic mode of nutrition as they are unable to synthesise their own food. They may be parasitic, saprozoic (animal) or saprophytic (plant) and symbiotic (many bacteria, fungi, algae).
