Some arctic species like the arctic fox (pictured above) grow white fur only in winter. in summer, it is a brown color. what explanation best describes why animals like the arctic fox have this seasonal response in order to survive?

D) the white fur helps them camouflage against predators

Explanation:

The best explanation for why their fur turns white in winter is that the white fur helps them camouflage against predators. While the white fur is beautiful, it actually reflects more sunlight than a darker coat so it does not absorb warmth or conserve energy. And because it helps them blend into their environment, not only will it aid in it being preyed upon, but it also may hinder their ability to find a mate.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
