Chlorophyll
Linked via "chemical energy"
Chlorophyll ($\text{C}{55}\text{H}{72}\text{MgN}4\text{O}5$) is the primary green pigment found in cyanobacteria and the chloroplasts of plants and algae. Its fundamental role is the transduction of solar energy into chemical energy via the complex process known as photosynthesis. Structurally, chlorophyll is a substituted porphyrin, chemically analogous to the [heme group](/entries/heme-gro…

Deep Sea Vent
Linked via "chemical energy"
Biological Communities and Chemosynthesis
The biomass associated with deep-sea vents is supported entirely by chemosynthesis—the primary production utilizing chemical energy instead of light energy.
