Original: "Frog eggs hatch into tadpoles in water, then adult frogs live on land."
Corrected (one sentence): "Frog eggs hatch into tadpoles in the water, and adult frogs live on land."
Or as two short sentences: "Frog eggs hatch into tadpoles in the water. Adult frogs live on land."
Why this is better (simple):
- We add "the" before "water" because we mean the water where the eggs are.
- We use "and" (or a period) to join the two ideas so the sentence sounds clear.
Quick frog life steps:
- Eggs → hatch into tadpoles (live in water)
- Tadpoles grow legs and become froglets
- Froglets grow into adult frogs (live on land)
Good job! You can say either corrected version—both are right.
