it depends its physical if you cut it and its chemical when you burn it
The decay of organic matter such as leaves is a chemical change.
Crushing a leaf is a physical change, not a chemical change because the chemical composition of the leaf remains the same before and after crushing. However, if the crushing process causes the leaf to release certain chemicals due to breaking of cell walls, then it can result in a chemical change.
The color change in a leaf typically indicates a chemical change when it results from the breakdown of chlorophyll and the revealing of other pigments, such as carotenoids and anthocyanins, as the plant prepares for winter. This process involves biochemical reactions that alter the pigments present in the leaf. Conversely, a physical change may be indicated if the color change is due to external factors like exposure to light or temperature without altering the leaf's chemical composition.
physical change because chemical changes usually cant be seen
Leaves change colour because the green pigment (chlorophyll) is degraded, then other pigments like anthocyanins (red or purple) and carotenoids (yellow) are exposed. So the change is more chemical than physical. Leaves going brown are also caused by chemical changes, but it also means the leaf cells are dead or dying.
Chemical
It is a chemical change, a degradation of the compounds from the leaf.
The change is leaf color is a chemical change.

Chemical. It has to do with the closing of the part that connects the leaf to the tree and the lack of nutrients causes the leaf to turn colours.
Making salt by mixing sodium and chlorine is it a physical or chemical which one

Photosynthesis makes a leaf green so when it turns brown it has stopped doing photosynthesis so most likely it is chemical change. Helpful enough? :|
Drying wood in a shed does not result in a chemical change because the process involves the removal of water through evaporation, which is a physical change. The structure and composition of the wood remain the same.
