Question

do just leaving water in sunlight create algae

Answer 1

Yes, leaving water in sunlight can create an environment conducive to the growth of algae. Sunlight provides the energy needed for photosynthesis, a process that allows algae to thrive and multiply rapidly in water bodies. Additionally, various nutrients present in water, such as nitrogen and phosphorus, combined with sunlight, can promote algae growth even further. Therefore, it is recommended to keep water containers covered or in shaded areas to prevent algae formation.
