Cyanobacteria

Stromatolites are deposited by this organism

What is the domain often called "extremophiles," meaning lovers of extremes such as hydrothermal vents?

Archaea

Bioluminescence

What is the term describing the light some fishes, squids, and other animals of the deep can produce?

Chemosynthetic

Autotrophs are called this if they derive energy from compounds such as hydrogen sulfide, nitrogen, and iron.

Nitrogen fixation

This is the process by which many planktonic cyanobacteria convert gaseous nitrogen to ammonium.
