The expression "fall off" is used to describe when something decreases or becomes less. For example, a person's interest in a hobby might "fall off" over time, meaning they become less interested in it. Or, someone's performance at work might "fall off" if they start making more mistakes or doing a worse job than before. It can also be used to describe a physical object becoming detached or dropping off, like leaves falling off a tree in the fall.
