What is an example of a primary consumer?

What is the warmest zone in the ocean? Why?
The Sunlight Zone is the warmest because of the sun.

Which part of the ocean floor is the deepest?
The ocean trench

What is the difference between a mixture and a solution? Give an example of each.
A mixture is a combination of two or more substances that do not lose their identifying characteristics when combined (chex mix) A solution is a mixture in which two substances are evenly mixed and you cannot see the different substances (water and salt).

How does salinity affect water density?
The higher the salt content in water, the more dense it becomes.
