Chlorophytes are an important portion of the [[phytoplankton]] in both freshwater and marine habitats, [[carbon fixation|fixating]] more than a billion tons of carbon every year. They also live as multicellular [[macroalgae]], or [[seaweed]]s, settled along rocky ocean shores.{{Sfn|Margulis|Chapman|2009|p=200}} Most species of Chlorophyta are aquatic, prevalent in both marine and freshwater environments. About 90% of all known species live in freshwater.{{Sfn|Lee|2018}} Some species have adapted to a wide range of terrestrial environments. For example, ''[[Chlamydomonas nivalis]]'' lives on summer alpine snowfields, and ''[[Trentepohlia (alga)|Trentepohlia]]'' species, live attached to rocks or woody parts of trees.{{Sfn|Graham|Graham|Wilcox|Cook|2022}}{{Sfn|Leliaert|Smith|Moreau|Herron|2012}} Several species have adapted to specialised and extreme environments, such as deserts, arctic environments, [[hypersaline]] habitats, marine deep waters, deep-sea [[hydrothermal vent]]s and habitats that experience extreme changes in temperature, light and salinity.{{Sfn|Lewis|Lewis|2005}}{{Sfn|De Wever|Leliaert|Verleyen|Vanormelingen|2009}}{{Sfn|Leliaert|Verbruggen|Zechman|2011}} Some groups, such as the [[Trentepohliales]], are exclusively found on land.{{Sfn|López-Bautista|Rindi|Guiry|2006}}{{Sfn|Foflonker|Ananyev|Qiu|Morrison|2016}}
