Bacteria Bacteria (singular: bacterium)
constitute a large domain of prokaryotic microorganisms
Typically a few micrometers in length, bacteria have a number of shapes, ranging from spheres to rods and spirals.
Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats.

Algae
Algae (Latin for "seaweed") are a very large and diverse group of eukaryotic organisms, ranging from unicellular genera such as Chlorella and the diatoms to multicellular forms such as the giant kelp, a large brown alga that may grow up to 50 meters in length.
