Answer 1

Answer:

In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.

Answer 2

RESPIRATION

• Respiration is the chemical process, which involves breathing in oxygen , breathing out carbon dioxide & breakdown of food using oxide to release energy.

DETAILED EXPLANATION

• All living organisms require energy to carry out various life processes . like nutrition, transport, excretion, reproduction, etc. This energy is stored in the food that we eat .
• In order to break down food to release energy oxidation of food takes place. This reaction takes place in the cells of the body of the organisms.
• The oxygen needed for the oxidation comes from the air that we inhale. This oxygen is then transported to every cell.
• Thus, the process in which food is broken down to release energy is called respiration. During respiration, carbon dioxide and water are released as waste - products.

Types of Respiration :-

• Aerobic respiration requires oxygen and releases lots of energy.
• Anaerobic respiration does not require oxygen and releases less energy.
