Why does female frog lay hundreds of egg?

Explanation

**Step-by-Step Text Solution:**

3. **Challenges of External Fertilization**: One of the main challenges of external fertilization is the high risk of gamete loss. Not all eggs will be fertilized, and many may be lost due to environmental factors or predators in the water.
