Question

2/10
why is the water cycle vital for life on earth?
it provides fresh water to plants and animals
it absorbs carbon dioxide
it forms dna and cell membranes
it converts nitrogen gas into usable forms

Explanation:

• Analyze each option:
• Option 1: The water cycle (evaporation, condensation, precipitation, etc.) redistributes water, providing fresh water (via precipitation, runoff, etc.) to plants and animals, which is essential for their survival (e.g., drinking, photosynthesis).
• Option 2: Absorbing carbon dioxide is mainly done by plants (photosynthesis) or the ocean, not the water cycle.
• Option 3: DNA and cell membranes are formed from molecules like nucleic acids and lipids, not the water cycle.
• Option 4: Converting nitrogen gas to usable forms is the nitrogen cycle, not the water cycle.

Answer:

A. It provides fresh water to plants and animals
