Verified
In which animals would diffusion alone not be an effective transport mechanism for gas exchange?
A) Nematodes
B) Sponges
C) Cnidarians
D) Annelids
E) Flatworms
Diffusion
The movement of particles from an area of higher concentration to an area of lower concentration, leading to an even distribution.
Gas Exchange
The biological process through which different gases (like oxygen and carbon dioxide) are transferred in opposite directions across a respiratory surface.
- Acquire knowledge about the morphological and functional modifications in diverse animal species that enhance gas exchange efficiency.

Final Answer :
D
Explanation :
Annelids, unlike the other animals listed, have a more complex and larger body structure that requires a more efficient gas exchange system than diffusion alone can provide. They have a closed circulatory system that aids in transporting gases to and from tissues, which is necessary due to their size and metabolic demands.
