In this discussion, you will justify the dependence of life on the sun and the interdependence of living things and their chemistry. People who do not understand the relationships between biological processes on the planet may roll their eyes at the statement, “Life on this planet is a delicate balance.” What evidence have you found in this course so far to support this statement?

The production and consumption of ATP during photosynthesis and cellular respiration.
