The Journal of Ecosystem and Ecography deals with the challenges facing ecosystems and their survival in co-ordination with the other components of nature. A typical ecosystem consists of living and non-living components. The living components are plants and animals and the non-living components are air, water and soil. An ecosystem can be defined as an interaction of the living and non-living systems in co-existence with each other. The living and non-living systems can also be said of as biotic and abiotic components. These biotic and abiotic systems are connected by nutrient cycles and energy flows. The abiotic components are sunlight, temperature, precipitation, water and soil. The biotic components are primary producers, herbivores, carnivores, omnivores and detritivores. The primary producers refer to the basic producers of enery i.e. plants. Plants through photosynthesis, are the primary producers of enerygy in the ecosytem. The primary energy of an ecosystem is obtained from the sun. The role of plants and animals in these ecosystems is to facilitate the transfer of energy and biomass from one organism to another thereby influencing processes such as decomposition and photosynthesis. th epprimary puprpose of an ecosystem can be thought of as to ensure the sustenance of survival of species in the ecosystem and therefore maintian a balance in the nature. Enery flow in the ecosystem is first dervied from the sun, as photons, then converted to carbohydrates by the process of photosynthesis. These carbohydrates are consumed by herbivores. Herbivores are in return consumed by carnivores and carnivores by detritivores. If one can calculate the carbohydrate molecuels at the end of the food chain, it is found that the energy present at the beginning of the food chain is much less at the end of the food chain.
