Why is the property of water expanding upon freezing important for aquatic life in cold climates? Group of answer choices It decreases the pressure on aquatic organisms living at great depths It causes ice to float, insulating the water below and protecting aquatic life from extreme cold It allows nutrients to become more concentrated in liquid water It increases the oxygen content in the water The expanding ice pushes phytoplankton lower into the water column, making it more easily accessible to those who survive on it
