Answer:
Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.
There are two types of Respiration:
Aerobic Respiration — Takes place in the presence of oxygen.
Anaerobic Respiration –Takes place in the absence of oxygen.
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
The respiratory rate is the rate at which breathing occurs. This is usually measured in breaths per minute and is set and controlled by the respiratory centre.
Breathing uses chemical and mechanical processes to bring oxygen to every cell of the body and to get rid of carbon dioxide. Our body needs oxygen to obtain energy to fuel all our living processes. Carbon dioxide is a waste product of that process.
