Explanation:
Detailed explanation-1: -Note: Amoeba, being a unicellular organism, obtains oxygen and expels waste gas (carbon dioxide) by diffusion. Thus, in amoeba diffusion is used as the method of respiration.
Detailed explanation-2: -They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Detailed explanation-3: -In single celled organisms diffusion is sufficient to meet all their requirements of food, exchange of gases or removal of wastes but it is not in case of multicellular organisms.
