Where do frogs spend most of their lives?

Frogs are amphibians, and their life cycle is closely tied to aquatic environments, especially during their larval stage when they are tadpoles. Most species of frogs spend a significant portion of their lives in or near water, which provides necessary conditions for breeding, feeding, and maintaining hydration. Frogs typically require water bodies, such as ponds or streams, for reproduction, as their eggs are often laid in water. This aquatic habitat is crucial for their development from eggs to tadpoles and then, eventually, into adult frogs.

While adult frogs can also be found on land, the emphasis on their reliance on water for the earlier stages of their life cycle highlights why the answer that indicates spending most of their lives in water is the most accurate.
