ya the accesive growth of algae in water bodies is known as algal bloom which is caused by the draining of acess fertiliser in water bodies
this causes death of aquatic life because this algae uses all the oxygen throughout life time but also after their death the oxygen decomposes bacteria also uses a massive amount of oxygen and leads to deficiency in dissolved oxygen and finally causes death of aquatic life
