### Step-by-Step Solution:

1. **Definition of Biodegradable Polymers**:
- Biodegradable polymers are materials that can be broken down by natural processes, such as the action of microorganisms (bacteria, fungi, etc.). These polymers decompose into natural substances like water, carbon dioxide, and biomass, thus minimizing environmental impact.

2. **Example of Biodegradable Polymer**:
- An example of a biodegradable polymer is **polylactic acid (PLA)**. PLA is derived from renewable resources like corn starch or sugarcane and is commonly used in packaging and disposable cutlery.
