cacti and other succulents are commonly found in deserts, where there is little rainfall. other xerophytes, such as certain bromeliads, can survive through both extremely wet and extremely dry periods and can be found in seasonally-moist habitats such as tropical forests, exploiting niches where water supplies are too intermittent for mesophytic plants to survive. likewise, chaparral plants are adapted to mediterranean climates, which have wet winters and dry summers.
