Ubiquitous Presence: Photosynthetic algae live in oceans, freshwater, and terrestrial settings. They are vital to planetary ecosystems.
Photosynthesis by algae produces much of Earth's oxygen. They create oxygen from sunlight and carbon dioxide to make carbohydrates.
Algae provide nourishment for aquatic organisms at the base of aquatic food chains. They feed various marine and freshwater organisms.
Phytoplankton, seaweeds, and lichens make up algae's astonishing biodiversity. Their diversity strengthens ecosystems.
Photosynthesis by algae sequesters carbon dioxide from the atmosphere. Helps minimize climate change.
Biotechnology: Algae can produce energy, remediate pollution, and extract colors, omega-3 fatty acids, and antioxidants.
Symbiotic Relationships: Some algae coexist with fungi in lichens. These alliances help them survive in varied situations.
Threats and Harmful Algal Blooms: Aquatic ecosystems depend on algae, yet some species can cause HABs under particular conditions. These blooms can poison aquatic life and humans.
