Is the releasing of light by a firefly endergonic or exergonic? Explain how such a process abides by the first and second laws of thermodynamics?

First law states energy can only be transferred and thus chemical energy is becoming light energy Second law states that in the conversion of energy, the total entropy/disorderness of a closed system increases over time, this is true as the firefly must acquire water and food using muscle energy and afterwards has a chemical reaction, showing that overall more disorder must occur for light to be made also exergonic energy since its being released into the environment
