Select the correct statement.

Options

A. Heterotrophs do not syntesise their own food.
B. Heterotrophs utilise solar energy for photosynthesis.
C. Heterotrophs synthesise their own food.
D. Heterotrophs are capable of converting carbon dioxide and water into carbohydrates.

Explanation

**Step-by-Step Solution:**

1. **Understand the Definitions:**
- **Heterotrophs:** These are organisms that cannot synthesize their own food and rely on other sources of organic carbon, primarily plants and animals.
- **Autotrophs:** These are organisms that can produce their own food from inorganic substances, using light or chemical energy. They perform photosynthesis.

2. **Analyze Each Statement:**
- **Statement 1:** "Heterotrophs do not synthesize their own food."
- This statement is correct. Heterotrophs obtain their food from other organisms.

- **Statement 2:** "Heterotrophs utilize solar energy for photosynthesis."
- This statement is incorrect. It is autotrophs that utilize solar energy for photosynthesis, not heterotrophs.

- **Statement 3:** "Heterotrophs synthesize their own food."
- This statement is also incorrect. Heterotrophs do not synthesize their own food; they rely on other organisms for nutrition.

- **Statement 4:** "Heterotrophs are capable of converting carbon dioxide and water into carbohydrates."
- This statement is incorrect. It is autotrophs that convert carbon dioxide and water into carbohydrates through photosynthesis.

3. **Conclusion:**
- The only correct statement is the first one: "Heterotrophs do not synthesize their own food."

**Final Answer:**
The correct statement is: "Heterotrophs do not synthesize their own food."
