The chaparral biome consists of different types of terrain such as mountains and plains. This biome is similar to the desert biome due to hot and dry conditions prevail in both the biomes, but chaparral biome receives more rainfall than the desert biome. This biome is characterized by having both forests and grassland with a large amount of biodiversity. The vast biodiversity insulate the biome from loss of single a single species. Thus, the chaparral biome is not too sensitive to the loss of a single species.
