Detailed explanation-1: -An algal bloom or algae bloom is a rapid increase or aggregation in the algae population of freshwater or marine water systems and is often identified by water discolouration of their pigments.
Detailed explanation-2: -Algae vary from small, single-celled forms to complex multi-cellular forms. An algal bloom is a rapid increase in the density of algae in an aquatic system. Algal blooms sometimes are natural phenomena, but their frequency, duration and intensity are increased by nutrient pollution.
Detailed explanation-3: -Algal blooms are dense layers of tiny green plants that occur on the surface of lakes and other bodies of water when there is an overabundance of nutrients (primarily phosphorus) on which algae depend. This effect is called eutrophication.
Detailed explanation-4: -An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems.
Detailed explanation-5: -A harmful algal bloom (HAB) occurs when toxin-producing algae grow excessively in a body of water. Algae are microscopic organisms that live in aquatic environments and use photosynthesis to produce energy from sunlight, just like plants.
