We expect a lake to be ______ in Fall with oxygen levels _____ with depth.
stratified; decreasing
well mixed; decreasing
well mixed; increasing
well-mixed; remaining constant
In Fall, we expect a lake to be well mixed with oxygen levels decreasing with depth.
This is because, during the fall turnover, the cooler surface water sinks and mixes with the deeper water, leading to a more uniform distribution of oxygen throughout the lake. However, oxygen levels typically decrease with depth due to factors such as decomposition and reduced light penetration.
So the best answer is: **well mixed;
