Question

incandescence is the term for light that comes from heat, such as the light of a candle. luminescence, by contrast, refers to light that comes from non - heat sources.

luminescence appears in several varieties. when a living organism, such as a jellyfish or insect, emits (sends out) light, this is called bioluminescence. this light is created through a chemical reaction that takes place in the organisms body. fluorescence, on the other hand, is when a substance absorbs light and then re - emits it, usually with a longer wavelength. phosphorescence is similar to fluorescence, except that there is a delay between the substances absorption of light and its re - emission of that light. this delay allows the substance to glow even after the source of light has been removed. phosphorescence is what makes glow - in - the - dark stickers shine brightly after the lights in a room have been turned off.

which term matches the picture?

image of an insect emitting light

options (partially visible): bioluminescence, fluorescence...

Explanation:

The picture shows a living organism (an insect) emitting light. According to the text, bioluminescence is defined as light emitted by a living organism (like a jellyfish or insect) through a chemical reaction in its body. Fluorescence involves a substance absorbing and re - emitting light, and phosphorescence has a delay in re - emission. Since the insect is a living organism emitting light, the term that matches is bioluminescence.

Answer:

bioluminescence
