Vedclass · Answer

(B) Terrestrial organisms have evolved specific excretory mechanisms to minimize water loss:$1$. Terrestrial animals produce less toxic substances like urea or uric acid instead of highly toxic ammonia,which requires large amounts of water for dilution.$2$. Mammals and many terrestrial amphibians are ureotelic,excreting urea,which requires significantly less $H_{2}O$ for elimination compared to ammonia.$3$. Reptiles,birds,and insects are uricotelic,excreting uric acid in the form of a dry paste or pellet. This process requires negligible amounts of $H_{2}O$,making it an excellent adaptation for water conservation in arid environments.
