The lives of the organisms in the desert require a substantial amount of survival skills. The temperature in a desert biome is always very high and it does not rain very often so it is also extremely dry. Any organisms that live in the desert must be able to adapt to these conditions in order to live. For example, one organism that can be found in the desert is cacti. Cacti roots are closer to the surface than other plants so it is able to drink the rain water. They also have think skins which are a protection from the heat along with the fact that its stems grow upward instead of outward protecting it from the sun (Big Site of Amazing Facts, 2013). The cactus is also an expert

In the desert biome, no organism would be able to survive without another organism. Their interactions are constant. Plants provide shelter and food for animals and animals help to pollinate and grow flowers (Bailey, 1999). One example of the interactions of organisms in the desert is between birds and other small animals and the cactus. Desert birds and animals that are small enough to navigate between cacti sharp needles use the cactus for shelter and for water. Another example would be how bats spread pollen from one part of a cactus to another part which helps the cactus grow flowers. The Joshua tree makes fruit in which animals eat, too. These are all examples of how organisms in the desert interact with each other. Although animals living in the desert have had to evolve in order to adapt to the desert conditions, those conditions are very fragile. The desert may be a hard place for non-natives to survive, but the desert’s ecosystem is very sensitive and not easy to regenerate. “Development, off-highway vehicle use, livestock overgrazing, construction of roads and utilities, military training exercises, air pollution and the spread of non-native plant species have seriously altered the desert ecosystem over the last century” (Barton, 1999). These are the hazards by humans that are directly affecting the ecosystem in the desert. According to Barton (1999) the off-highway vehicle use, construction, overgrazing, and military usage damages the desert’s
