Answer:
The conclusion is that different matters have different biomass percentages.
Explanation:
Different matters have different biomass percentages because they are formed from different elements. each biomass is formed from the elements such as carbon, oxygen, hydrogen and nitrogen. for example, the human body is composed of 30 percent of biomass while 70 percent is water. the percentages of different elements are carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%) and phosphorus (0.14%). At each level, only 10 percent of biomass is transferred to another level and remaining 90 percent releases in the form of heat.
