No not really - most tropical rainforest trees are evergreens and keep their color until the leaves fall off. Certain palm trees do not change color until they die, or fall off too. Eventually yes, but Conifers have smaller leaves so they change slower.
All leaves will eventually drop off trees... there is no real way to prevent that from happening. Leaves die and gravity does the rest. However, trees in the tropical rainforests are not deciduous-- meaning they do not drop all of their leaves in autumn. Because it is summer year-round in the tropical rainforests, there is no autumn and the leaves do not change colors or all fall at once.
I believe all maples lose their leaves in the fall but certain oak trees keep their leaves all year. The "live oak" is named such because it keeps its leaves through the winter.
Before leaves change color in the winter and fall, they are usually green. But after they change the leaves can be a variety of colors including: yellow, brown, orange, red, leaves with many colors on them, and etc. Some can be spotted with browns and/or blacks and many leaves have holes in them or are moldy. Many colorful leaves on the ground are dried out and crunch when you walk on them. You can also keep these leaves over the years for looking at, displaying, and etc. You can press them.
deciduous trees go into dormancy over winter relying on stored energy to survive, without the leaves they cant photosynthesize. the exception to this would be in young trees that have green stems that photosynthesize.
the leafs on a pine tree don't change colour they stay green all year but the rest of them change colour like the hardwood trees
Trees lose their leaves all the time, but rainforests do not shed their leaves all at once.
The area was a deciduous forest, and all the trees would change colors in the fall.
Deciduous trees lose all their leaves in the Autumn.
Leaves change color because the trunk of the tree stops sending nutrients and water and other chemicals to the leaves. In the winder, the tree keeps all the nutrients inside and doesn't have the energy to keep feeding the leaves, so they change color and die and fall off. Trees with leaves that do not change color just means that they don't have this process and are most likely in a warmer climate or survive much better in cold
No. I do not know of any Maple species that are Evergreen.
The other name for Autumn is Fall probably because all the leaves fall at that time of year!
