In comparing a desert to a marsh, which statement is not true? 1. a desert has more biodiversity than a marsh. 2. many organisms in deserts and marshes exhibit convergent evolution. 3. the temperature and moisture of a desert vary more from one place to another. 4. physical conditions in a marsh vary less from place to place.

 1. A desert has more biodiversity than a marsh.

A desert is an area exhibiting hot and dry climatic conditions. A desert is a biome which exhibit low precipitation rate as a result of this it possess low diversity of life forms. Marsh is a wetland that is situated near the edges of lakes and streams. Marshes form a transition regions between aquatic and terrestrial regions. The availability of water in the marshes supports the life of many life forms.

Hence, on comparing a desert to a marsh, a desert has more biodiversity than a marsh.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
