Food chains, also called food webs, food networks and/or trophic networks, describe the feeding relationships between species to another within an ecosystem. Organisms are connected to the organisms they consume by arrows representing the direction of biomass transfer. Typically a food chain or food web refers to a graph where only connections are recorded, and a food network or ecosystem network refers to a network where the connections are given weights representing the quantity of nutrients or energy being transferred.

A report which talks about the current stage of the logistics industry in Hong Kong and its challenges. A nice example in the video is a logistics company to deliver cooked rice for an extra cost to a fast food chain.

great example of global warming

Algae, at the base of the food chain, for example, rely on fish to cycle back into the water such nutrients as nitrogen and phosphorus, which are otherwise locked up in animal or plant cells. Fish excrete dissolved nutrients back into the water, making them available to algae, which need them to grow.
