**Step-by-Step Solution:**

1. **Definition of Plants as Autotrophs**:
- Plants are classified as autotrophs, meaning they can produce their own food. They do this through a process called photosynthesis, where they convert sunlight, water, and carbon dioxide into glucose (food) and oxygen.

2. **Photosynthesis Process**:
- During photosynthesis, plants use chlorophyll (the green pigment in leaves) to capture sunlight. This energy is then used to convert water (absorbed from the soil) and carbon dioxide (taken from the air) into food.
