Illustrates the relationship between humans and ecosystems

As humans we are part of ecosystems; we interact with the environment and other species, even though it may not always be for the better. We mostly are destroying ecosystems through activities like deforestation, overfishing, etc. We are also a consumer in all food chains/food webs.

there really is life in the deepest part

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.
