bioluminescence is a ___ reaction. physical chemical mechanical acid - base

Explanation:

Bioluminescence involves the production of light by living organisms through chemical processes (e.g., reactions in organisms like fireflies or plankton that produce light via biochemical reactions). Physical reactions don't involve new substance formation, mechanical is about force/motion, and acid - base is a type of chemical reaction but bioluminescence is a broader chemical process. So it's a chemical reaction.
