Which body part of the camel shrinks and retains its size depending on the consumption of food?

• A. Rough tongue
• B. Long eyelashes
• C. Hump
• D. Neck

The body part of the camel that shrinks and retains its size based on food consumption is the hump. This unique feature stores fat, which the camel can use as energy when food is scarce. When the camel eats, the hump can become larger, and when it goes without food for a while, the hump shrinks as the fat is utilized.

Understanding the Camel's Hump

The hump is not just a storage area; it plays a crucial role in the camel's ability to survive in harsh environments. Here are some key points:

• Fat Storage: The hump is primarily made of fat, which provides energy.
• Water Conservation: By using fat for energy, camels can conserve water, as fat metabolism produces water.
• Adaptation: This adaptation allows camels to thrive in deserts where food and water are limited.

Other Features of Camels

While the hump is significant, camels have other interesting features:

• Rough Tongue: Helps in eating tough desert plants.
• Long Eyelashes: Protects their eyes from sand and dust.
• Neck: Provides flexibility and helps in reaching food.

In summary, the hump is a remarkable adaptation that allows camels to survive in extreme conditions by adjusting in size based on their food intake.
