The most important abiotic factor which influences the desert ecosystem is rainfall. Most deserts are characterized by the fact that it experiences little or no rainfall. The deserts receive a total of less than 300 mm of rainfall per year, where a rainforest receives about 2000 mm. The lack of rain, and ultimately water in a desert makes the vegetation scarce and influences the adaptation of the plants and organisms. Plants such as cacti which are very common in a desert ecosystem have adapted to the scarcity of water by storing water in their stems. The saguaro cacti do not have very deep roots, allowing it to soak up rain and dew before it evaporates. It’s spongy surface inside expands to hold more water (Cunningham n.d.). Bushes develop small and few leave, but long roots to adapt to the harsh conditions by conserving water. Some plants are short lived and grow only during when rain is available.
