Many animals obtain energy by eating the surrounding vegetation, however, desert plants are much more difficult for organisms to consume. [10] To avoid intense temperatures, the majority of small desert mammals are nocturnal, living in burrows to avoid the intense desert sun during the daytime.
The Sonoran Desert. The Sonoran Desert is a North American desert and ecoregion which covers large parts of the southwestern United States and of northwestern Mexico. With an area of 260,000 square kilometers (100,000 sq mi), it is the hottest desert in Mexico. The western portion of the Mexico–United States border passes through the Sonoran ...

Some desert plants produce seed which lies dormant in the soil until sparked into growth by rainfall. With annuals, such plants grow with great rapidity and may flower and set seed within weeks, aiming to complete their development before the last vestige of water dries up. For perennial plants, reproduction is more likely to be successful if ...
These organisms play a crucial role in benthic ecosystems, forming essential food chains and participating in the nitrogen cycle. [8] Detritivores and decomposers that reside in the desert live in burrows underground to avoid the hot surface since underground conditions provide favorable living conditions for them.
It is common [2]: 7 to find areas where a layer of pebbles is left after wind and water removes the lighter gravels and sand, and the pebbles are cemented together with desert varnish, causing landforms called desert pavement that are impenetrable to many species. Unlike in the Arizona Upland where trees are common, they are mostly absent ...
The Summary. Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions.
An adult desert locust can eat about 2 g (0.1 oz) of plant material each day, so the billions of insects in a large swarm can be very destructive, stripping all the foliage from plants in an affected area and consuming stems, flowers, fruits, seeds and bark. [49]
