done

Explanation:

• "It ensures life on Earth can exist": Water is essential for life's processes, so this applies.
• "It is a part of all organic compounds": Organic compounds have carbon; water (H₂O) isn't organic, so this is incorrect.
• "It is used by plants for photosynthesis": Plants use water in photosynthesis (6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂), so this applies.
• "It is the main component of many biological components, including blood": Blood is ~90% water, and many biological structures have water, so this applies.

Answer:

• It ensures life on Earth can exist.
• It is used by plants for photosynthesis.
• It is the main component of many biological components, including blood.
