What exact month or day do leaves fall?
There is no single answer to that. Leaves obviously mainly fall in autumn. Autumn lasts a few months and it is autumn in the southern hemisphere at a different time of the calendar year than in the northern hemisphere. Many leaves fall in winter and some can also fall in spring and summer too. Things like extreme weather or other natural events or disease can cause leaves to fall. So leaves can actually fall in any month and on any day.
Why do leaves of deciduous fall in the autumn?
Deciduous trees lose leaves in autumn because of the changing conditions in climate (warm to cooler temperatures) and light reduction as days are growing shorter. These factors cause a problem in water transport from the ground and can lead to dormancy in deciduous trees.

Why do some leaves have two colors on them?
Leaves have different pigment molecules that are necessary for the process of photosynthesis. The pigment molecules reflect different colored wavelengths from the sun. For example Chlorophyll reflects green wavelengths. The reflected wavelengths reach eyes and cause the leaf to be different colors.
Is leaves turning color in the fall a chemical or physical change?
I don't know the scientific equation, but I do know that the tree withdraws it's sugars from the leaves, during the autumn and winter to make sure that there is enough for the main tree. The withdrawal of the sugars is a physical action, but it is a chemical one as well. The chlorophyll that was made thru the sunlight on the leaves for photosynthesis. This stops when the weather turns colder and there is less sunlight causing the leaves lessen the amount to chlorophyll they can make, signaling to the tree to cut off the sugar supply to the leaves. I'd say it's both. Also, You have witnessed a spectacular chemical change if you have seen the leaves on a tree change from green to bright yellow, red, or orange. But, it is not a change from a green pigment to a red pigment, as you might think. Pigments are chemicals that give leaves their color. In autumn, however, changes in temperature and rainfall amounts cause trees to stop producing chlorophyll. The chlorophyll already in the leaves undergoes a chemical change into colorless chemicals.Where do the bright fall colors come from? The pigments that produce fall colors have been present in the leaves all along. However, in the summer, chlorophyll is present in large enough amounts to mask these pigments. In the fall, when chlorophyll production stops, the bright pigments become visible.
What is an autumn leaf that has 2 or more colours called?
Autumn foliage In the fall The amount of chlorophyll in the leaves begins to fade. Normally chlorophyll overpowers the color of other substances, such as carotenoids, which are natural pigments in leaves. But chlorophyll levels drop, the green fades, and the other pigments begin to show their colors.

What is the cause for seasons of a deciduous forest?
Seasons are caused by weather changes and lessening of sunlight. Leaves change colors because they aren't producing chlorophyl (what makes plants green.)
