The chain itself only has chemical energy equal its weight and material. Then it'll have a bit of potential energy depending on where it's kept. If it's turning it'll have a bit of kinetic energy as well.
Energy enters a food chain in the form of sunlight, which is converted into chemical energy by producers through photosynthesis. When energy leaves a food chain, it is typically in the form of heat after being used by organisms for metabolism and daily functions.
Bicycle
how is the energy in a food chain different form the energy of the wind?
The form of energy represented by x when an electric fan is turned on is electrical energy. This is the energy that powers the fan and is converted into mechanical energy, which allows the fan blades to rotate and create airflow.
A bicycle gives off kinetic energy when it is in motion, as the energy of its moving parts is transferred to the surrounding environment. The rider's pedaling also generates some heat energy, but the predominant form of energy given off by a bicycle is kinetic energy.
The form of energy represented by a book falling off a desk is gravitational potential energy being converted to kinetic energy as the book accelerates towards the ground.
kinetic
A bicycle converts mechanical energy generated by pedaling into kinetic energy to propel the bike forward. It can also be considered a form of human-powered transportation, where the energy source is the rider's own physical effort.
Conservation of momentum.
kinetic
The form of energy passed along from organism to organism in a food chain is chemical energy. This energy is derived from the organic compounds present in the food consumed by each organism.
