Which one of the following ways of acquiring nutrients is not characteristic of fungi?
(a) Saprophytic
(b) Parasitic
(c) Autotrophic
(d) Heterotrophic

Options

A. Saprophytic
B. Parasitic
C. Autotrophic
D. Heterotrophic

Explanation

To solve the question, "Which one of the following ways of acquiring nutrients is not characteristic of fungi?" we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Fungi**:
- Fungi are eukaryotic organisms that have various modes of nutrition. They do not have chlorophyll and cannot perform photosynthesis.

2. **Analyzing the Options**:
- **(a) Saprophytic**: This mode of nutrition involves obtaining nutrients from dead and decaying organic matter. Fungi are well-known for being saprophytic, as they play a crucial role in decomposition.

- **(b) Parasitic**: This mode involves obtaining nutrients from a living host organism. Many fungi are parasitic, deriving their nutrition from their hosts, often causing diseases in plants and animals.

- **(c) Autotrophic**: This mode of nutrition involves producing one's own food, typically through photosynthesis. Fungi do not have the ability to synthesize their own food and are not autotrophic.

- **(d) Heterotrophic**: This mode means obtaining food from other organisms. Most fungi are heterotrophic, as they rely on other organic sources for their nutrition.

3. **Identifying the Incorrect Option**:
- From the analysis, we can see that options (a), (b), and (d) are all modes of nutrition that fungi exhibit. However, option (c) is not characteristic of fungi, as they do not produce their own food and are not autotrophic.

4. **Conclusion**:
- The correct answer is **(c) Autotrophic**.

### Final Answer:
(c) Autotrophic
