6. HOTTER WATER HOTTER WATER When the temperature of the water increases it´s harder for oxygen to disolve in it, so some acuatic animals can die. Also, they are not adapted to this warmer temperature. When the temperature of the water increases it´s harder for oxygen to disolve in it, so some acuatic animals can die.
