Algae are microscopic organisms that live in aquatic environments and use photosynthesis to produce energy from sunlight, just like plants. Harmful algal bloom (HAB) – overgrowth of phytoplankton (cyanobacteria or microalgae) that can cause harm to animals, people, or the local ecology. A harmful algal bloom (HAB) occurs when toxin-producing algae grow excessively in a body of water. Now customize the name of a clipboard to store your clips. Harmful algal blooms (HABs) occur when algae — simple photosynthetic organisms that live in the sea and freshwater — grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. The study of algal blooms spans over ten orders of magnitude, from the level of chemical signals (nanometer scale) and single cells (micrometer scale) to the large-scale oceanic blooms (kilometer scale). Adverse effects: Economic (e.g., beach closures, shellfish harvest closures) Ecologic (e.g., oxygen depletion, sunlight deprivation) Health (e.g., human and animal illnesses) Harmful . • harmful algal blooms (HABs) Common characteristics • Algae is a term describing any non-vascular primary producer • All take in nutrients (N, P, etc.) • Algal blooms refers to the uncontrolled growth of certain microalgae, which in turn leads to the production of toxins, disruption of the natural aquatic ecosystems.
