Answer: Fungus like protists are heterotrophic and feed on organic matter.
Cellular slime mould is a species of fungus like protists that form slug.
Explanation:
Fungus like protists are heterotrophic and the feed on organic matter and mostly unicellular.
Cellular slime mould are protists belonging to class Dictyostelia. They are heterotrophic and decomposers that live on organic matter. When there is deterioration condition, the cells migrates together to form slugs and move to form new habitat. Some of the cells form stalk and others form spores.

Bioluminescence is the phenomenon which is seen in the dinoflagellates which is very common. It is caused due to chemical reactions that takes place inside the organism.
There is an influx of protons in the cell which drops the pH of the cell. It is the oxidation of luciferin which produces the glow.
This phenomenon acts as a shock for the predator because it is in the form of flash for less than 20 microseconds.This flash reduces the number of dinoflagellates which is being eaten by the predator.
