Solution

Yes, the desert toad, like most amphibians, does require water for reproduction. Here are the steps explaining why:

  1. Mating: The process begins with the male desert toad attracting a female for mating. This usually happens in or near a water source.

  2. Fertilization: After mating, the female lays her eggs in the water. The male then fertilizes these eggs. This process is called external fertilization and is common in many amphibian species, including the desert toad.

  3. Development: The fertilized eggs remain in the water where they develop into tadpoles. This stage of the life cycle is entirely aquatic.

  4. Metamorphosis: The tadpoles undergo metamorphosis, during which they develop legs and lungs for life on land. However, until this process is complete, they are reliant on the water environment for survival.

  5. Adult Life: Once the metamorphosis is complete, the young toads can survive in the desert environment. However, they will return to the water to reproduce and continue the cycle.

So, while adult desert toads are adapted to live in arid environments, water is a crucial part of their reproductive cycle.
