Well as you might know, water is one of the most important abiotic factors essential for life. Without water, consumers would have nothing to drink. The plants under the water body might die too as they wouldn’t be able to photosynthesize. If the plants die, there’s less oxygen for the tiny water creatures. Some water creatures might die as well. If other animals don’t have water to drink, they’re going to die as well. Therefore, without water, most biotic factors would probably die due to the lack of efficiency in them performing life processes like photosynthesis and cellular respiration.
