Question

Explain why frogs are restricted to a moist environment.

a) To prevent desiccation and aid in respiration through the skin
b) To enhance vision in low-light conditions
c) To regulate body temperature efficiently
d) To avoid predation by amphibious predators

Answer 1

Frogs need a moist environment to prevent water loss through their skin and to breathe properly, as their skin is vital for cutaneous respiration.a) To prevent desiccation and aid in respiration through the skin

Step-by-step explanation:

Frogs are restricted to a moist environment primarily to prevent desiccation and aid in respiration through their skin. This is because frog skin is moist and permeable, covered with mucous glands, allowing for cutaneous respiration. A dry environment can lead to water loss through their skin, making it essential for frogs to stay near water or in moist areas to maintain their skin's moisture and proper functioning. Additionally, some mucous glands also produce toxins to deter predators.
