The sun provides light energy which plants use to convert in to chemical energy through photosynthesis. Nutrients from the soil also assist in growth of plants. Animals rely completely on these green plants for their energy. Green plants produce chemical energy (food energy).
The basic unit of energy that scientists use is the joule (J). It is equivalent to the energy transferred when a one-newton force acts over one meter distance.
Units of energy used in science include the Joule and the calorie.Joules are the most commonly used form and are included in the SI unit. The calorie is still frequently used in food and nutrition sciences. Although they have different values, they are otherwise interchangeable and either may be used.
Calories. Actually the unit called Calorie in food energy is the Kilocalorie, ie 1000 calories.
The recommended unit for any type of energy is, of course, the joule. The older unit, calorie, is still often used for food. If spelled with a capital "C", "Calorie", it usually means a kilocalorie.
Calories are the unit of energy used to measure how much energy is present in food. One calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
I believe it's still calories... ---- It depends what you're measuring.The basic unit of energy in science is the joule.In food science, the amount of energy that a food may release is measured in calories or joules.

Calorie is the unit used to express chemical energy in food.
The basic unit of energy that scientists use is the joule (J). It is equivalent to the energy transferred when a one-newton force acts over one meter distance.
Any unit of energy can be used to describe the energy content of food.
cell. A cell is the smallest unit of life that can carry out all the processes necessary for an organism to function. It contains the biological machinery needed to perform essential functions like growth, energy production, and reproduction.
Energy is measured in joules.
