Final answer:
Smaller animals experience a greater concern for evaporative water loss due to their larger surface area to volume ratio. They can reduce water loss through evaporation by cooling the air they exhale.
Step-by-step explanation:
Evaporative water loss (EWL) is more of a concern for smaller land dwelling animals than larger ones. Smaller animals have a larger surface area to volume ratio compared to larger animals, leading to more rapid water loss through evaporation. One way animals can reduce EWL is by cooling exhaled air, which can conserve water by reducing the amount of water vapor lost during respiration.
