Why do large organisms need transport systems but small ones do not?

I know that small organisms have a small surface area to volume ratio but why does that mean direct diffusion is possible for them?

Because there's less distance to outside their body
Just think how long it would take for us to take a breath if you had to wait for oxygen to diffuse from outside your body to your lungs

No it is to do with the the distance yes, but its mainly due to the size of the organism for diffusion to take place as said by treejoe4 another reason why is that the process needs therefore a transport system, as smaller organisms can diffuse on a smaller distance.
