Radiolarians have existed since the beginning of the Paleozoic era, producing an astonishing diversity of intricate shapes during their 600 million year history.
The central capsule . . enclosed in a membrane . . contains not only the nucleus but mitochondria (respiratory organelles) and Golgi bodies (secretory organelles), as well as vacuoles, lipid droplets, and food reserves. Reproduction, respiration, and biochemical synthesis are functions carried out in the central capsule.

Phytoplankton are also crucially dependent on minerals.
While almost all phytoplankton species are obligate photoautotrophs, there are some that are mixotrophic and other, non-pigmented species that are actually heterotrophic (the latter are often viewed as zooplankton).
The term phytoplankton encompasses all photoautotrophic microorganisms in aquatic food webs.
...unlike terrestrial communities, where most autotrophs are plants, phytoplankton are a diverse group, incorporating protistan eukaryotes and both eubacterial and archaebacterial prokaryotes.
There are about 5,000 known species of marine phytoplankton.

A bacteriophage (from 'bacteria' and Greek φᾰγεῖν phagein "to eat") is any one of a number of viruses that infect bacteria. Bacteriophages are among the most common biological entities on Earth.[1] The term is commonly used in its shortened form, phage.
In July 2007, the same bacteriophages were approved for use on all food products.[17] Government agencies in the West have for several years been looking to Georgia and the Former Soviet Union for help with exploiting phages for counteracting bioweapons and toxins, such as anthrax and botulism.
