Answer: While active transport requires energy and work, passive transport does not.
Explanation:
During respiration, members of the animal kingdom use oxygen and then release carbon dioxide as a waste gas.
Members of the animal kingdom have a respiratory system that is composed of muscles, and airways that functions together to transport air into lungs, and the oxygen is used by cells. Carbon dioxide is also transported away from the cells as a waste gas. Respiration relies on other systems, such as the circulatory system, to transport oxygen and carbon dioxide to and from cells.
Large ecosystems always have higher biodiversity than smaller ecosystems. A large area of a forest will likely have higher biodiversity than a smaller area of a small area and small ecosystems always have low biodiversity.
