The diagram illustrates the processes by which small and large Venus Flytrap species capture and digest small prey, highlighting differences in their use of digestive enzymes.
Overall, the smaller Venus Flytrap captures and digests prey more quickly, while the larger species takes longer and ultimately releases the prey without digestion.
In the case of the smaller Venus Flytrap, when the prey touches the trigger hairs, the trap snaps shut rapidly. This action triggers the release of digestive enzymes that begin breaking down the prey. The plant then absorbs the nutrients, and once digestion is complete, the trap reopens.
In contrast, the larger Venus Flytrap responds similarly at first; when the prey contacts the trigger hairs, the trap closes. However, no digestive enzymes are released, and after some time, the trap reopens, releasing the prey unharmed. This suggests that the larger species may be more selective or conservative in its use of digestive energy, possibly optimizing for larger prey.
