A food web is more accurate than a food chain. Animals eat different things, and are eaten by different things, a web will show all or most of its predators and prey, whereas a food chain will only show one predator and one prey.
A food chain is typically considered an open loop system because it involves the flow of energy and nutrients from producers to consumers and decomposers, without a closed cycle. In an open system, energy and matter are exchanged with the environment, allowing for continuous input and output. In contrast, a closed loop system would recycle all components without external inputs. Therefore, a food chain represents an open loop system.

A chain hoist uses gears to multiply force.A chain hoist is operated by hand. An operator pulls the light loop chain on the side of the chain hoist. This turns a gear mechanism inside the chain hoist housing to turn the chain pulley. When this pulley turns, it raises the heavy chain which usually has a hook on the end. By pulling the light chain loop, the manual hoist is actually able to increase the force that is being applied by the heavy chain. This is caused by the gear ratios inside the manual chain hoist. The mechanical work done by the operator is the same as the work done by the heavy lifting chain.
