Part 4/6:
Incorporating insights from modern science, Professor Brian Cox explains the pivotal role of photosynthesis as the entry point for order in the biosphere. Through photosynthesis, organisms convert sunlight—an ordered energy source—into biomass, which is then transformed into a variety of ordered structures.
During a compelling segment filmed in a Palauan lake, Cox highlights the extraordinary relationship between jellyfish and symbiotic algae. The algae perform photosynthesis, utilizing sunlight to convert water and carbon dioxide into sugar—an ordered molecule. This biological process exemplifies how life sustains itself by generating order from seemingly chaotic natural forces.
