Where do most algae live?
The majority of algae live in aquatic habitats (Current Biology, 2014). Yet, the word “aquatic” is almost limited in its ability to encompass the diversity of these habitats. These organisms can thrive in freshwater lakes or in saltwater oceans.
Where is green algae mostly found?
fresh water
Most green algae occur in fresh water, usually attached to submerged rocks and wood or as scum on stagnant water; there are also terrestrial and marine species. Free-floating microscopic species serve as food and oxygen sources for aquatic organisms.
Why are algae found mostly in water?
Algae help to ‘purify’ water by absorbing nutrients and heavy metals from streams and rivers. Algae are the basis of most aquatic food webs. They are food for many small aquatic invertebrates, and in turn, these small creatures are food for larger animals such as fish.
Where are most marine algae found?
Seaweeds are found along coastal areas, living on the floor of continental shelves and washed up in intertidal zones. Some seaweeds drift with plankton in the sunlit surface waters (epipelagic zone) of the open ocean. Back in the Silurian, some phytoplankton evolved into red, brown and green algae.
Which alga is commonest green?
The Chlorophyta include the early diverging prasinophyte lineages and the core Chlorophyta, which contain the majority of described species of green algae. The Streptophyta include charophytes and land plants.
Where are algae mostly found in land or water?
Algae are mostly found in water bodies like ponds, lakes, rivers and seas.
Where does algae live in the ocean?
Algae require warmth, sunlight, and nutrients to grow and reproduce, so they live in the upper 60 to 90 meters (200 to 300 feet) of ocean water. The upper layer of water, the epipelagic zone, is rich in oxygen, penetrated by sunlight, and warmer than water at lower levels.
Where do macro algae live in the world ocean?
Diversity of Great Barrier Reef Macroalgae They occupy a variety of habitats, including shallow and deep coral reefs, inter-reefal areas, sandy bottoms, seagrass beds, mangrove roots, and rocky intertidal zones. Some algae are even endolithic, living inside the skeletons of corals, and other reef substrata.
