PLEASE HELP 2. Do you think rapid or gradual environmental changes have a greater potential to affect
an organism's niche? Explain your answer.

ofc it does !!

Explanation:

when the environment changes that specific animal niche will most likely change due to it being such a drastic change. for example when let's say the hunting rates have increased alot and that results in the drastic decrease of mice, well that was the main source of food that the foxes were getting and will make the move environments and change their diet drastically cause they cant find their regular diet. i hope this is what u were asking !

"a.) well–developed vascular system."
