concentration of the nutrients on the top layer, because all the nutrient will

We can see in this graph the two main layers
separated and there is a change in the
temperature at different depths in the lake, in addition of the temperature,
the nitrogen separate (it is known that there are two types of nitrogen, the
atmospherical nitrogen and thedissolved
The red section shown in the graph is the warm
water, the blue section is the cold water, and we can see the sharp raise of
the temperature between the layers.

the global warming, that rise the temperature all around the world.
What is the preference of the algae that lives
