Respiration is a process of degradation of complex organic compound with the production of carbon dioxide, water and energy.
Respiration involves two phases, which are;
(1). External Respiration or Breathing: this is a process in which
animals take oxygen in and release carbon dioxide.
(2). Internal Respiration or Cellular Respiration: this process involve the release of energy from food substance with the release of carbondioxide and and water.
Single celled animals or unicellular animals such as amoeba exchange gases through cell surface. The STRUCTURE X IS THE PLASMA MEMBRANE. There is absorption of of Oxygen from the surrounding air or water,hence, giving out carbondioxide through plasma membrane by Diffusion.
PS: Lung is used in respiration process in Human
