Adaptations for transport

Why can larger organisms NOT rely on diffusion alone for transport?

A
  • Increased surface area to volume ratio
  • Diffusion distance is too short to supply surface cells
B
  • Decreased volume to surface area ratio
  • Diffusion occurs too rapidly to supply deep-seated cells
C
  • Decreased surface area to volume ratio
  • Diffusion distance is too great to supply deep-seated cells
D
  • Increased surface area to volume ratio
  • Diffusion requires too much energy to supply deep-seated cells
