What is response to stimuli
A lake freezes during the winter. The ice forms on the surface while fish and other organisms continue living in the liquid water below. Explain why this happens and why it is important.
Ice is less dense than liquid water, so it floats. The ice forms an insulating layer that helps keep the water underneath from freezing completely, allowing aquatic organisms to survive.
