macroalgae

Macroalgae, commonly known as seaweeds, are large, plant-like organisms that grow in aquatic environments like oceans and seas. Unlike tiny algae, macroalgae are visible to the naked eye and come in various shapes and colors, such as green, brown, and red. They play a vital role in marine ecosystems by producing oxygen, providing habitat for marine life, and serving as a source of food for many species, including humans. Macroalgae are also used in products like thickeners, biofuels, and fertilizers, highlighting their ecological and economic importance.
