The top journals of Ecosystem, deal with the key issues that need attention in the field of Ecosystem. An analysis of the energy transfer at the end of the food chain leads to the conclusion that the transfer of energy is inefficient. The intricate network of these food chains with each other and different ecosystems is called a food web. The level of an organism in the hierarchy of the food chain is called a trophic level. The measure of the trophic level is taken as the number of steps the organism is, from the start of the food chain. The efficiency of transfer of biomass and energy from one organism to another is called ecologial efficiency. The many processes of energy flow and nutrient recycling are controlled by the geological and chemical factors of the earth. The study of the influence of these factors on biotic and abiotic components of the earth is called biogeochemistry. This study helps the ecologists to analyse environmental problems such as: pollution, greenhouse effect, acid rain and global warming. In order to study and tackle these problems, every single component of the ecosystem needs to be broken down an calculated. Some of these parameters are element ratios, mass balance and element cycling.
