The nutrients cycle of an ecosystem is where energy and matter transfer between living organisms and nonliving parts of the environment. When animals and plants consume nutrients found in the soil, these nutrients are released back into the soil via decomposition of animals and plants. They are necessary to the lives of people, plants, animals, and all other organisms
Nutrients have six major groups
Most foods contain most nutrients, in different amounts
Carbohydrates provide energy for the body. Nearly all the carbohydrates we eat come from plants. They include starches found in cereals, grains, and plants like potatoes. Sugars, found in fruits, vegetables, and milk, are also carbohydrates.
Fats provide more than twice as much energy as carbohydrates. They also help protect the body and its internal organs. Common fats include vegetable oils, such as soybean, cottonseed, and corn oil. Fats that come from animal products include butter, eggs, milk, cheese, meats, poultry, and fish also contain high levels of fats.
Proteins are the body’s essential tissue-builders. They help in maintaining healthy skin, bones, muscles, and blood. Proteins regulate bodily processes, including transporting oxygen and nutrients into and out of human body cells to prevent the clotting of blood. Proteins help in the formation of antibodies, which help fight diseases and strengthen the immune system.
Minerals and vitamins are called “Micronutrients” because they are needed in very small quantities compared with carbohydrates, fats, and proteins, which are also known as macronutrients. Minerals provide building materials for the body and help regulate its activities, much as proteins do. Calcium and Phosphorus build strong bones and teeth. Iron contributes to healthy blood, and Iodine helps keep the thyroid gland working properly.
Vitamins help the body make full use of other nutrients. Essential Vitamin B1 helps regulate the release of energy from carbohydrates, promotes a healthy appetite. Vitamins also aid in the functioning of the nervous system. Vitamin D aids in the growth and maintenance of healthy bones.
Other essentials for the body’s health include Water, Oxygen, and Fiber. Water makes up more than half of a human body’s weight. Water is involved in most body processes. For example:- the regulation of temperature of the human body, the transporting of nutrients into human body cells, and the elimination of waste products from human body cells. Oxygen is not a nutrient, since it is breathed in and not eaten, but it is essential to life.
Fiber is an indigestible material found in food. It adds bulk to the diet and helps to keep our intestines healthy. Fiber-rich foods include whole grains, dried beans, and fresh fruits and vegetables.
