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

Terrestrial insects minimize water loss by having a cuticle covered by a waxy hydrophobic layer, which helps to prevent water from evaporating from their bodies. Keeping the spiracles open would actually increase water loss, as these are the openings through which insects exchange gases with the environment. Eating more plant material high in water content would provide temporary relief, but does not address the long-term issue of water conservation. Excreting nitrogenous waste as urea is a mechanism used by some animals for excretion, but it is not directly linked to water conservation.
