The Desert Biome is an ecosystem that forms due to the low level of rainfall it receives each year. It is located in North Africa, and some of its sand dunes can reach almost two hundred meters in height. Competition is when two species rely on the same limited resource, one species will be better adapted than the other to benefit from the resource. Deserts and grasslands both receive low amounts of rainfall compared to other biomes. This causes pollution and is harmful to the animals living near the oil wells.
