1. how does the density of ice compare to that liquid water and why is that property important to aquatic oranisms
a. the density of ice is higher than that liquid water, which means that ice forms from the bottom of lakes upward , protecting aquatic life in waterI***
b. the density of ice is lowery than that of liqurd water, which means hat ice forms from he top of lakes downward, protecting aquatic life in witer
