Explanation:

Question 1 (The word autotroph means)

• Option A describes a heterotroph (organisms that can't make their own food, e.g., animals).
• Option B: Autotrophs (like plants, algae) use processes like photosynthesis/chemosynthesis to produce their own food, so this matches the definition.
• Option C describes a food web, not autotroph.
• Option D describes matter, not autotroph.

Question 2 (The word heterotroph means)

• Option A ("self - nourishing") is the definition of autotroph.
• Option B: Heterotrophs (e.g., animals, fungi) rely on consuming other organisms for food as they can't produce it themselves, so this is correct.
• Option C describes autotroph.
• Option D describes a food web, not heterotroph.

Answer:

B. an organism that produces its own food
