Their Relatives, Affect on Humans, and Role in the Food Chain
A Diatom
Chrysophyta are algae, so their closest relatives are the six other divisions of algae: Euglenophyta, Pyrrophyta, Chlorophyta, Rhotophyta, Paeophyta, and Xanthophyta. Being the main components of plankton and nanoplankton, diatoms and chrysophyceae are the foundation of the marine food chain, functioning as the producers.
Chrysophyta can be considered helpful to humans. We use them in toothpaste, scouring products, and filters. As autotrophs, they provide a substantial amount of the oxygen in the atmosphere, as well. Also, because chrysophytes store their food as oils, they can be used for biofuel. Diatoms are especially effective in biobutanol production because of their small size.
