HELP PLS Danielle lives with her family on a farm. In school, she has been learning about the nitrogen cycle in science class. She knows that her father spread a nitrogen-based fertilizer on a patch of grass recently where the cows graze in the field. Why was it necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass? a. because nitrogen can only be “fixed” by lightning
b. because there are no decomposers on the farm
c. because bacteria released all of the nitrogen into the air
d. because plants cannot use “free” nitrogen

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.
