Because the more complex an organism become the more surface area to volume ratio.This means that unlike simple organism(like insects) who rely on diffusion for transport of oxygen and nutrients is readily available due to their excellent surface area to volume ratio. However if an organism has a bad surface area to volume ratio(larger organisms) they require a more efficient flow of oxygen and nutrients throughout their body.
