Having only a three-chambered heart puts a large restraint on the amount of heat that is produced inside the body. Similar to those of the past reptiles, lizards will tend to colonize in open areas where there is a large amount of direct sunlight. Direct sunlight will greatly warm a reptile’s body so that they can perform their basic metabolic functions with more ease. The blood pressure of a lizard is also very low due to their hearts; as a result, lizards have grown to not need a continuous food supply but still eat in bulk like their predecessor(Dowling). In many cases, lizards that have a diet of an herbivore located in dessert biomes have been found to eat cactus fruit and low growing flowers. With the integration of plants into their diet, lizards easily control small plant populations throughout many desserts of the
