How does food provide a source of energy for living things Brainly?

When organisms consume food, it is broken down to release energy and to obtain building blocks for other molecules. During this process, oxygen is consumed and some carbon is given off as carbon dioxide. Inside living things, some of the energy is used to maintain the body and conduct reactions necessary for life.

Why is food important for living things?

Organisms need to take food to get energy and perform life processes. A living organism undergoes many life processes like nutrition, respiration, digestion, transportation, excretion, circulation of blood, and reproduction. To perform all these life processes the organism needs energy and nutrients.

How do living organisms obtain energy from food Class 7?

All the organisms (plants and animals) require energy for performing various activities and maintaining their life. This energy is obtained by the breakdown of digested food during the process of respiration. The process of releasing energy from food is called respiration.

What are the materials needed in respiration?

Oxygen and Glucose are the two main raw materials that are needed in cellular respiration. This respiration is a type of respiration in which the glucose that we take in is converted into energy as ATP

What are raw materials of respiration?

Glucose molecules

What is the major source of energy for cells?

the Sun

Why is glucose the main energy source?

Glucose is one of the primary molecules which serve as energy sources for plants and animals. When oxidized in the body in the process called metabolism, glucose produces carbon dioxide, water, and some nitrogen compounds and in the process provides energy which can be used by the cells.

Is glucose a source of energy?

In energy metabolism, glucose is the most important source of energy in all organisms. Glucose for metabolism is stored as a polymer, in plants mainly as starch and amylopectin, and in animals as glycogen. Glucose circulates in the blood of animals as blood sugar.
