Paleontology. A microfossil is a descriptive term applied to fossilized plants and animals whose size is just at or below the level at which the fossil can be analyzed by the naked eye. A commonly applied cutoff point between "micro" and "macro" fossils is 1 mm. Microfossils may either be complete (or near-complete) organisms in themselves ...
The organisms responsible for primary production are called primary producers or autotrophs . Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen.

These tiny living things help supply oxygen and food to other organisms that live in the ocean. They even help keep the ocean clean.
Jan 29, 2021 · The role of benthic microbes in rivers and streams can be generally characterized by the microbial loop shown in figure 30.17. In contrast to the microbial loop in planktonic systems, the benthos of a lotic system, such as a fast-moving river or stream, features small eukaryotes such as invertebrates and insect larvae.
The book Marine Protists: Diversity and Dynamics gives an overview of current research on the phylogeny, cytology, genomics, biology, ecology, fisheries, applied sciences, geology and pathology of marine free-living and symbiotic protists. Poorly known but ecologically important protists such as labyrinthulids and apostome ciliates are also ...
Microorganism. A cluster of Escherichia coli bacteria magnified 10,000 times. A micro-organism or microbe is an organism which is microscopic, which means so small that people cannot see them with the naked eye. The study of microorganisms is called microbiology. Micro-organisms include bacteria, fungi, archaea, protists and viruses, and are ...
