Nutrients provide organisms w/essential components for cellular processes required for maintenance, growth and survival. Carbon and other elements combine to form simple molecules to complex molecules (organic molecules) Carbon chains form the skeletons of most organic molecules. Carbon chains vary in length and shape. Organic molecules consisting of only carbon and hydrogen. Many organic molecules, such as fats, have hydrocarbon components. Hydrocarbons can undergo reactions that release a large amount of energy. C, h, and o compounds primarily come from plants. This makes up 96. 3% of the elements in the human body. Iron (blood), calcium (bones, teeth), sodium (nerves), potassium (nerves), copper (enzymes), iodine (thyroid)
