The leaves lose their chlorophyll, leaving the underlying color. Yellow is the color of carotene, while red is because of the sugar content.
Deciduous trees change the color of their leaves before they fall off in autumn.
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.

Yes. Chameleons are polychromatic because they can change color to match the trees, leaves, and ground around them.
Deciduous trees change the color of their leaves before they fall off in autumn.
Trees whose leaves change color in fall are called deciduous trees. These trees undergo a process of senescence, where chlorophyll breaks down, revealing other pigments like carotenoids and anthocyanins that produce vibrant colors. Common examples include maple, oak, and birch trees. This seasonal change is part of their adaptation to survive colder months.
Usually at the end of September or early october.
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
