Question
Chapter 30.1, Problem 3CC
Summary Introduction
To determine: The difference between primary production in lakes and coastal ecosystems and in the open ocean.
Introduction: Primary producers prepare their food through the process of photosynthesis such as green algae and plants. Photosynthesis is a process of fixing carbon dioxide by the synthesis of
