Practice problem
Why is water density important to lake habitats during cold months?
Density helps maintain a stable water temperature throughout the year.
Water density allows minerals and nutrients to float throughout the lake and be easily accessed by organisms.
Density allows a layer of ice to float above the liquid water, insulating the habitat below.
The layer of ice at the top captures nutrients and preserves them until temperatures rise.
Type a concept, like “slope” or “photosynthesis”.
