Chemical Potential Energy
The levels of a food web represent the energy.
chemical
The arrows represent the flow of energy.
We humans (as well as animals) get the energy we need from our food. This energy is stored in the food, in the form of chemical energy.
Food has chemical energy.
Food has chemical energy.
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.
Transfer of energy
The form of energy stored in food is called chemical energy. This energy is released when the bonds in food molecules are broken down during digestion.
Calories are units of energy provided by food.
How energy moves from organism to organism.
The energy used to cook food in a microwave is a form of electromagnetic energy. Microwaves emit radiation in the form of electromagnetic waves that cause water molecules in the food to vibrate, generating heat and cooking the food.
