Different habitats pose certain challenges to animal survival. For instance, terrestrial insects must maintain water balance by minimizing evaporation. How do insects minimize water loss?

Question

Quizplus · Accepted Answer

Insects minimize water loss by having a cuticle covered by a waxy hydrophobic layer, which acts as a barrier to water loss through evaporation. This layer helps to seal in moisture and prevent water loss from the body. Eating more water-rich plants, excreting nitrogenous waste as urea, or keeping the spiracles open would not be effective strategies for minimizing water loss in terrestrial insects.
