Energy Dynamics in Human Ecosystem: Energy Consumption

摘要

The results showed that energy intake from different sources varied widely at the trophic levels. The autotrophic villages consumed much less energy than that of the heterotrophic village. Again, total energy consumption from various sources differed markedly within the autotrophic villages. The per capita total energy consumption through different sources was much higher (1123 MJ/day) among the heterotrophs as compared to those of the autotrophs (70.6 MJ/day). The autotrophic villages also differed markedly in per capita total energy consumption through different sources (55.3 MJ/day to 99.7 MJ/day). Taking per capita total energy consumption as the assessment of the economic status of the users, the study indicated better living standard of the heterotrophs than that of the autotrophs.
