Final Approach
For Macro Mondays theme 'Leaf'.
In my garden there are several small downy birch trees with leaves that are beginning to turn yellow and fall off. I collected a couple of handfuls of leaves, then chose one of the smallest for this image.
Deciduous trees lose their leaves before the winter season when the temperature is too low for photosynthesis to occur. The green chlorophyll degrades causing the leaves to turn colour. The leaves are no longer necessary, so they fall off the tree in a process known as abscission.
