Which term refers to taking in a substance from the surroundings, commonly used in biology?

• A. Fertiliser
• B. Pesticide
• C. Absorb
• D. Device

Answer: (C)

Absorb describes the process of taking in a substance from the surroundings. In biology, absorption is how nutrients, water, or gases cross membranes into an organism or into cells, such as water and minerals taken up by plant roots or nutrients absorbed in the small intestine, or oxygen absorbed in the lungs. The other terms refer to items rather than a process: fertiliser and pesticide are substances used in agriculture, not the act of taking in, and a device is an object, not a biological uptake process. So absorb is the best fit for describing the act of uptake from the surroundings.
