The key takeaway is that various substances have distinct biomass proportions. Variations in biomass percentages exist due to the differing elemental compositions of these substances. Each biomass is constituted by elements like carbon, hydrogen, nitrogen, and oxygen. For instance, the human body comprises 30% biomass, while the remainder consists of water. The breakdown of various elemental percentages includes carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%), and phosphorus (0.14%). At every level, only 10% of biomass is transferred to the next level, with the remaining 90% being dissipated as heat.
