Components of Aquatic Ecosystems

Lets get ready for a warm up!

Open Ended

How is the littoral zone able to sustain more plant life compared to the Limnetic Zone? Add as many details as possible.

Lets get ready to answer some questions!

• Question #1: If I add 36.24 ppt to a water container filled with 6.00 mL of D.O., why does the oxygen level drop down to 5.50 mL?

• Question #2:Warm water holds less oxygen compared to cooler water, please explain why.
