#### Part 2: Why is water important to plants, animals, and humans?

Answer:
Water is essential for life because:

- For Plants:
Water helps plants absorb nutrients from the soil, supports photosynthesis, and keeps them upright. Without water, plants wilt and die.

- For Animals:
Animals need water to drink, regulate body temperature, digest food, and carry out metabolic processes. Most animals depend on water sources like rivers, lakes, or oceans.

- For Humans:
Humans need water for drinking, cooking, cleaning, and maintaining health. Our bodies are made up of about 60% water, and we require it daily to survive.

> 💡 Summary: Water is vital for survival, growth, and all biological processes in living organisms.
