Chapter 30.2, Problem 2.2RIA
Summary Introduction
To describe: Two recently recognized sources of organic nitrogen in the open ocean.
Introduction: There are different species of cyanobacteria, which fixes organic nitrogen in water by the process of biological nitrogen fixation. The species of different cyanobacteria are Richelia intracellularis, Trichodesmium, Crocosphaera watsonii, and Synechococcus. These species of cyanobacteria are the sources of organic nitrogen in an open ocean.

Every type of organism in the upper ocean contributes to both recycling of organic matter and sinking of organic matter. Briefly describe 2 interactions between organisms that result in both the recycling and sinking of organic matter.
a) Interaction 1:
- Brief description of how this interaction results in both the recycling of organic matter in the upper ocean and the sinking of organic matter:
b) Interaction 2:
- Brief description of how this interaction results in both the recycling of organic matter in the upper ocean and the sinking of organic matter:.
Why are nitrogen-containing molecules limited in the biosphere? Give two reasons.
Refer to Fig. 5.5. and redraw the important transformations of fixed nitrogen in ecosystems. Note the following processes: biological N fixation, non-biological N-fixation, ammonification, nitrification, denitrification.
