3. under which type of change would more organisms be able to survive? why?

Most animals are well adapted to their biotic and abiotic conditions due to behavioural, physiological or structural adaptations that increase their chances of survival and reproduction. I looked it up for you

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
