The human body's optimal water level is approximately 72%. This varies slightly from individual to individual but fluctuations based on water intake and loss.

The water level gets disrupted. The level of water in water bodies get changed.
The oxygen level varies in different bodies of water because some bodies of water are warmer than others therefore,.. the more hot the less oxygen because the particles will begin to die as the water gets hotter but this is how it becomes a compressed gas ...
The optimal level of output is where marginal costs = marginal damages.

arousal level
The equilibrium gets maintained during water cycle. The water in the water bodies gets evaporated to maintain the sea level.
the optimal level of advertising expenditure for the firm is determined where the marginal revenue increase in costs of advertising are equal to the marginal increase in revenue
"Optimal" can be defined in various ways. When looking from a profit maximization viewpoint, the level of production with the highest (return/cost) ratio will be the optimal. However, when looking purely from a productive viewpoint, the optimal level would be the one with the highest (output quantity/input quantity) ratio
There are no locks in the Suez Canal as it connects two bodies of water that are at the same level
google. That tells you everything.
