Hint: Food is any substance that is consumed to provide nutritional support to an organism. Food is typically derived from plants, animals, or fungi and contains essential nutrients such as carbohydrates, fats, proteins, vitamins, and minerals.
Complete answer: The substance is consumed by an organism and assimilated by the organism's cells to provide energy, sustain life, or stimulate growth. Different species of animals have different feeding behaviors that satisfy the needs of their unique metabolisms, and these feeding behaviors have frequently evolved to fill a specific ecological niche within specific geographical contexts.
Plants are the source of the majority of the food. Some food is obtained directly from plants, but even animals used as food sources are raised by feeding them plant-based food. Cereal grain is a staple food that produces more food energy than any other crop on the planet. Corn (maize), wheat, and rice – in all their varieties – account for 87 percent of global grain production. The majority of the grain that is produced worldwide is fed to livestock.
Importance of food:
-It provides our bodies with all of the essential nutrients such as proteins, vitamins, carbohydrates, fats, and minerals. When our body gets the energy to metabolize in our body and our body functions properly, all nutrients provide energy to our body.
-When we are injured or ill, the food we eat provides our bodies with the nutrients they need to grow and heal.
-Plants and animals are the two main sources of our food.
-We eat leafy vegetables, fruits, and plant parts such as stems and roots.
-Animals provide us with milk, eggs, meat, chicken, fish, prawns, beef, and pork, among other things.
Types of essential foods:
-Carbohydrate (carbs) is one of the body's primary nutrients.
-Proteins are organic compounds made up of the elements oxygen, carbon, hydrogen, and nitrogen.
-Fats are the body's third most important nutrient source.
-Vitamins perform a variety of vital functions in our bodies, including increasing the growth of several organs and aiding in the maintenance of the diet.
Note: A functional food has been given an additional function (often one related to health promotion or disease prevention) by the addition of new or more existing ingredients. The term may also refer to traits that have been purposefully bred into existing edible plants, such as purple or gold potatoes with higher anthocyanin or carotenoid contents.
