Why is it necessary to sow seeds at appropriate depth?

Explanation

### Step-by-Step Solution:

1. **Understanding Seed Sowing**: Sowing seeds at the right depth is crucial for their growth and development. The depth at which seeds are sown can significantly affect their ability to germinate and thrive.

2. **Consequences of Superficial Sowing**: If seeds are sown too close to the surface (superficially), they can face several challenges:
- **Birds and Pests**: Seeds that are not buried deep enough are more susceptible to being eaten by birds and other pests. This can lead to a significant reduction in the number of seeds that germinate and grow into plants.
- **Improper Spacing**: Superficial sowing can lead to improper spacing between seeds. This can result in overcrowding, where plants compete for resources, leading to stunted growth.
