Which term describes an action by an organism or part of an organism causing a change in position or place?

• A. Ingestion
• B. Movement
• C. Excretion
• D. Osmosis

Answer: (B)

Movement is the action that causes a change in position or place. It covers how an organism or a body part moves from one location to another, or changes the orientation of a limb, driven by muscle activity. Ingestion is taking in food, excretion is getting rid of waste, and osmosis is the movement of water across a membrane based on water potential, not a change in the organism’s position. So the term that best fits the description is movement.
