Question

why is necessary to eat food​

Answer 1

to gain energy in the form of ATP which we get from our daily diet . ATP is used for all the activities we do

Answer 2

The foods we eat provide us with a range of nutrients: vitamins, minerals, water, fat, carbohydrates, fibre, and protein. These nutrients are put to different uses — as building materials to construct the tissues and organs from which our bodies are made; as the components of the molecular machinery that keeps our cells running as they should. All of these uses are unified by a common theme: a requirement for energy to make them happen. And this is where one particular type of nutrient comes into its own.
