Read the text. 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 organism's 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 substance's 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? fluorescence bioluminescence phosphorescence

Introduction:

Bioluminescence is the phenomenon of production and emission of light by a living organism.A large number of marine entities show bioluminescence wherein the colour that is emanated is usually green or blue and in a few cases the red colour is also observed. Apart from marine organisms, bioluminescence is also observed in the land entities, precisely invertebrates such as fireflies, worms, larvae – insects.
