Endothermy is just another word for the term "warm-blooded" and ectothermy is closest to the meaning of "cold-blooded." The obvious pros of endothermy is the ability to perform more activities within a larger range of temperatures. For example, a human would be able to walk around in 100 degree weather Fahrenheit. They would probably be sweating a lot to maintain body temperature and would require lots of water, but they could do it. In contrast, a Lizard would most likely be forced to stay in the shade under a rock or another place as they have no system for maintaining their body temperature, and thus would have to wait until the environmental temperature cooled down before they could find food or move around. The cons of endothermy is it requires a lot more energy for an organism to maintain homeostasis, which is also a pro of ectothermy as lizards and similar ectothermic organisms can utilize more of their energy to d food or move around. Hope this helps!
I’m pretty sure the answers are a. & c. Sorry if I’m wrong
Since stomata are affected by [CO2] and water vapor content of the air, an environment with high water vapor content (water potential) and high CO2 levels will likely have the highest #of stomata. I.e. when plants have readily available water source and ample CO2 in order to maximize photosynthesis. As far as geographic environment I think it varies quite a bit and there are competing hypotheses from what I understand
