A jellyfish you would think uses water in lots of ways. Not in these sections! Obviously you know that the jellyfish live in the water. They also drink water just like humans. Unlike us, the jellyfish breed in the water. Also, jellyfish actually are 90% water. Jellyfish have to swim in water, but humans call swimming playing. If jellyfish had a brain they would think that is weird! Another thing jellyfish don't do is they really don't keep clean. Jellyfish actually don't need to clean themselves. We do though because we don't live in water like jellyfish. Jellyfish eat plankton. The plankton is very small and it lives in water. Those are some ways that jellyfish use water.

Questions

1.   Why is water considered a "Natural Resource?"
2.   How is water essential (required) to our survival and the survival of all living things?

Answers

1. Water is considered a natural resource because it is made by nature. We can't make it either.
2. It is required for are survival because then if we didn't drink it we could die from thirst. Also we could not stay clean and it would be so dirty we would die.
