What are three ways that protists are beneficial?

1-Protists produce almost one-half of the oxygen on the planet through photosynthesis,

2-decompose and recycle nutrients that humans need to live,

3-make up a huge part of the food chain.

this is math not biology xd

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.
