Whichecological roles is/are played by at least some fungi?

Predation, decomposition

Explanation:

Fungi is very much important for the environment and play an important role in balancing the environment because they play many ecological roles. All fungi are heterotrophs so they depend on others to get their food.

One of the most important roles played by fungi is of decomposers. Most of the fungi are saprophytes and they get their nutrition from dead and decaying organic matter. So by doing this, they help in nutrient cycle and bioremediation.

Some fungi also play the ecological role of predators and prey on amoebas, roundworms, and rotifers, animals, etc. Therefore correct answer is predation and decomposition

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.
