How is complete digestive tract different from incomplete digestive tract?

Explanation

### Step-by-Step Solution:

1. **Definition of Digestive Tracts**:
- A complete digestive tract has two separate openings: one for the intake of food (mouth) and another for the expulsion of waste (anus).
- An incomplete digestive tract has only one opening that serves both functions, meaning food enters and waste exits through the same opening.

2. **Structure**:
- In a complete digestive system, the digestive process occurs in a linear fashion, allowing for specialization of different sections (like the stomach and intestines) for various functions such as digestion and absorption.
