Differentiate between Photoautotrophs and chemoautotrophs

Explanation

### Step-by-Step Solution

1. **Definition**:
- **Photoautotrophs**: These are organisms that synthesize their own food using sunlight. They utilize light energy to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis.
- **Chemoautotrophs**: These organisms obtain energy from chemical reactions involving inorganic substances. They synthesize their food through a process called chemosynthesis, using energy derived from the oxidation of inorganic molecules.

2. **Energy Source**:
- **Photoautotrophs**: They rely on light energy (sunlight) as their primary energy source for photosynthesis.
