👉 A intake is a process by which a substance enters or comes into contact with an organism. It can be thought of as a way for substances to enter and interact with living organisms, such as plants, animals, or even microorganisms in the environment. Intake refers to the action that occurs when a substance enters a living organism. This could involve absorption, excretion (the removal of substances from the body), or any other process through which substances are delivered into an organism's cells or tissues.
