Options

A. autotrophic
B. insectivorous
C. saprophytic
D. parasitic

Answer

### Step-by-Step Solution:

1. **Identify the Organisms**: The question mentions three organisms: yeast, mushroom, and bread mold.

2. **Understand Their Characteristics**: These organisms do not contain chlorophyll, which is essential for photosynthesis. Chlorophyll allows plants to synthesize their own food from sunlight.

3. **Determine Their Mode of Nutrition**: Since yeast, mushrooms, and bread molds lack chlorophyll, they cannot perform photosynthesis and thus cannot produce their own food.

4. **Classify Their Nutrition Type**: These organisms depend on other sources for their nutrition. They feed on organic matter, particularly from dead and decaying material.

5. **Define the Term**: The mode of nutrition that involves feeding on dead and decaying organic matter is known as **saprophytic nutrition**.

6. **Conclusion**: Therefore, the term used for the mode of nutrition in yeast, mushrooms, and bread molds is **saprophytic**.
