A fungal infection that covers an amphibian's skin can quickly kill the animal. Why can't amphibians tolerate their skin being covered with a foreign substance? A. Amphibians produce blood in their skin, and become anemic when the skin is covered by fungus B. Amphibians have small lungs and use their skin for gas exchange; they suffocate when the skin is covered with fungal growth C. Amphibians with fungal infections starve when the fungus absorbs all the food stored in their skin D. Because amphibians hear with their skin, those with fungal infections on the skin lose the ability to hear approaching predators E. Since amphibians use their skin for water storage, they dehydrate when an infectious fungus covers the skin and drains it of moisture

B. Amphibians have small lungs and use their skin for gas exchange; they suffocate when the skin is covered with fungal growth
