The carbon that plants need for photosynthesis comes

The carbon that plants need for photosynthesis comes from carbon dioxide, or CO2 that's present in our atmosphere. Carbon dioxide is released into the air by organisms, such as animals that undergo cellular respiration. In other words, we breathe out CO2 as a waste product. A large amount of carbon dioxide in the air also comes from the oceans and from the burning of fossil fuels.

Plants take in that carbon dioxide from the air, and take in water (H2O) as well. Photosynthesis produces a chemical reaction that creates glucose, or C6H12O6, out of CO2 and H2O. This is a life-giving process, as the sun's energy is stored within the glucose, and oxygen is released from plants during this reaction.

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.
