Final answer:
Camels are useful in the desert because they are strong and can go without water for long periods of time. Their feet are also well-adapted for navigating the sandy desert terrain.
Step-by-step explanation:
Camels were useful in the desert for several reasons. One of the main reasons is that they are strong and can go without water for long periods of time. This makes them well-suited for surviving in arid environments with limited water sources. Additionally, their feet have wide, flat pads that provide good traction on the sandy desert terrain, allowing them to walk more easily in the desert compared to horses.
