Why is the zone of aeration termed as such because it can support plant life because it is unsaturated because it is filled to its maximum level with water because it touches the surface

The second Option is correct i.e

By definition, the zone of aeration is layer of Earth where the pores and cracks are filled with air and water. It is sub-earthen region that exists between the Earth's surface and water table. This zone mainly comprises porous soil & rock. The pores in this layer are usually partially filled with water, while rest of them are filled with air. Thus, in this layer, air and water are able to interact with each other, leading to aeration of water. Therefore, this zone is known as zone of aeration.

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.
