Why can a cactus in the desert live without water for 2+ years, but the cactus on my desk needs to be watered regularly?

I’ve heard it has something to do with conditions, but this seems counterintuitive since the desert conditions are much harsher (hotter, drier) than those in my house, so if anything you’d think it would require less water.

Might be a different kind of cactus. Not all plants that look like that live in deserts, although most of them do. And even fairly dry deserts usually don’t go *years* without rain (those that do, like the Gobi or the Atacama, usually don’t have very many plants).
