Algae are mostly aquatic but are also found in other habitats. Some of the examples are given below.
Some other interesting habitats are listed below.
- Planktons. These are passively floating masses of plants (phytoplanktons) and animals (zooplanktons). Phytoplanktons consist mostly of diatoms.
- Red sea. It is a part of the mediterranean sea, where a blue green alga, Trichodesmium to grows on surface and imparts red colour.
- Red snow. Chlamydomonas nivalis and Haematococcus (green algac) inhabit ice or snow and develop red colour, hence the name red snow.
- Sargasso sea. It is a part of Atlantic Ocean, west of Africa, where broken fragments of Sargassum (brown alga) float on the surface.
- Water blooms. Blue green algae viz., Microcystis, Anabaena, Nostoc, etc., grow in abundance due to addition of nutrients to alter reservoirs. As a result, the water surfa is cove with bubbling masses of algae called water blooms.
- Red tide. Gonyaulax (red dinoflagellate undergo rapid multiplication and they make the sea appear red. Hence, it causes, what is popular known as red tide. Another dinoflagellate Karenia brevis (=Gymnodinium) common in Gulf of Mexico waters is responsible for Florida red tide.
