What is A: sea water. It is loaded with mineral salts and weighs about a pound and a half more per cubic foot than fresh water at the same temperature.
this is how we measure productivity
What is dissolved oxygen content
bacteria returns extra nitrogen back into the atmosphere; this is known as?
what is denitrification
Earth's major reservoir of carbon in the form of carbon dioxide.
what is the atmosphere
How is water essential to living things?
3 things im looking for ...
what is reproduction, what is growing and a necessity for all living things
This only happens during the "dark bottle stage", 9explain in detail)
What is diffusion of oxygen, because oxygen is being used in respiration but no photosynthesis is happening. this signifies respiration
this is the way nitrogen is fixed and able to use in the atmosphere.
