Answer

### Step-by-Step Solution:

1. **Understanding the Anatomy of Frogs**: Frogs are amphibians that have a unique body structure. One notable feature is the absence of a neck. This anatomical trait is significant for their movement and survival.

2. **Function of the Absence of Neck**: The absence of a neck in frogs allows for a streamlined body shape. This shape is advantageous for their jumping ability, which is crucial for both hunting and escaping predators.

3. **Jumping Ability**: Frogs rely heavily on their powerful hind legs for jumping. The lack of a neck helps them to maintain balance and stability while they leap. This jumping ability is essential for catching prey and avoiding threats.

4. **Amphibious Lifestyle**: Frogs are adapted to live both in water and on land. Their body structure, including the absence of a neck, supports their dual lifestyle, allowing them to move efficiently in both environments.

5. **Conclusion**: The absence of a neck in frogs primarily aids in their jumping ability, which is vital for their survival in the wild. Therefore, the correct answer to the question is that the absence of a neck helps frogs in jumping on the ground.
