Answer:
As we know water is the vital liquid on earth, this means that life is not possible without it. Even our own body is 70% water, for living organisms, including ourselves, allows them to properly self regulate, that is to say, facilitates organic processes such as digestion, absorption of nutrients, elimination of toxins as well as maintaining body temperature among other functions.
Taking this into consideration we can proceed to analyze the question. The lack of water would impact the whole planet if we are talking of total disappearance, even the planet atmosphere would change drastically, leading every living organism to death, if we consider only the lack of edible freshwater, we would have some organisms that could survive such algae, some plants, bacteria, and protozoans, but in the case of animals would lead to certain death, due to dehydration and a total cease of body functions. aquatic animals such as fish in the ocean would not be impacted in this way as their environment wouldn't be affected, on the other hand in the first scenario a total loss of water in the planet including oceans, logically would lead to death of every sea creature.
Hope this Helps!
