* Many components: Carrots are made up of various components, including:

* Water

* Carbohydrates (sugars, starch)

* Fiber

* Vitamins (A, K, C, etc.)

* Minerals (potassium, magnesium, etc.)

* Pigments (carotenoids)

* Not chemically bonded: These components are not chemically bonded together in a fixed ratio. Their proportions can vary slightly depending on the type of carrot, growing conditions, etc.

In contrast, a substance is a single, pure element or compound with a fixed chemical composition. For example, water (H₂O) is a substance because it always has the same ratio of hydrogen and oxygen atoms.
