Ecosystem and food network
An ecological view of food products focuses on describing the interactions between the food supply chain processes and the biotic and abiotic environment through illustrating how these processes affect the absorption, transfer, and losses of carbon and nutrients from the ecosystem. However, due to a scarcity of detailed information in this area, the ecological analysis of the food supply chain is very complex in time and space, and frequently, some spatial and temporal elements are overlooked in the effort to find an appropriate scale to express the ecology of the food supply chain.
