A-Level AQA Biology Cell Structure: Explain the advantage for larger

Question

Explain the advantage for larger animals of having a specialised system that facilitates oxygen uptake.

**Answer:** Larger organisms benefit from having a specialized system for oxygen uptake primarily due to the need for efficient gas exchange. As size increases, the surface area-to-volume ratio decreases, making diffusion less effective. A specialized system, such as lungs or gills, provides a larger surface area for oxygen absorption, facilitating faster and more efficient diffusion. This ensures that larger animals can meet their metabolic needs and maintain homeostasis despite the increased demands for oxygen.
