Chapter 15, Problem 5RQ
Summary Introduction
To review:
The method by which oxygenic phototroph maintains CO2 (Carbon dioxide) at a sufficient level in order to conduct the Calvin cycle.
Introduction:
Phototroph is the organism that is able to make their own food by trapping light from the Sun as a light source. Oxygenic phototroph get oxygen for the reduction of CO2 from water molecule. The oxygenic phototroph splits the water molecule in order to get oxygen for respiration.
