Calories are units of energy provided by food.
To derive energy from food you must eat foods that contain
Fossil fuels contain chemical energy.
geothermal 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.
liquids contain energy in the form of heat
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.
Food does NOT contain energy , it is converted to energy in the body as in calories
Batteries are a form of stored energy. They contain chemical energy that can be converted into electrical energy when needed.
Fossil fuels contain energy that originally came from the sun, which was absorbed by plants through photosynthesis millions of years ago. This energy is stored in the form of carbon compounds in fossil fuels such as coal, oil, and natural gas. When these fuels are burned, they release this stored energy in the form of heat and light.
Chloroplasts are the organelles in plant cells that turn energy from sunlight into food through the process of photosynthesis. They contain chlorophyll, a pigment that absorbs light energy and converts it into chemical energy in the form of glucose.
