Evergreens don lose their needles. How does that adaptation help them?
Evergreen trees do lose their needles. They just have a special way of doing it. Instead of losing them all at once, they lose them a little at a time. In fact, you could almost say that they shed their needles. As the old fall away, new needles take their place. Because they have green “leaves” all the time, they are able to start their food factories back up quickly … without taking the extra energy to grow leaves. That is one of the reasons that evergreen trees are better able to survive in places where there is not as much water available or where it is colder.
