The diagram illustrates the way that the huge and small-sized Venus Flytrap species process small prey to maximize their enzyme digestion.
Overall, both types of plant work on a trap-and-digest mechanism. However, while the small plant eats all the prey, the large plant is more selective in choosing the prey. This difference is to ensure the optimal function of digestive enzymes.
Regarding the tiny traps, when the prey comes inside and touches the hairs, they catch a signal, alarming the trap closes immediately. After finishing to trap the prey, the enzymes are released and begin the digestive process. Finally, enzymes decompose the prey into nutrients, allowing the plant to absorb essential nutrients.
On the other hand, while the lager trap also has the same process as the tiny one, the primary difference is in choosing the prey to digest. Specifically, the snaps are not tightly sealed, reopens and frees the insect if they know the prey size is small. In contrast, when the prey is big enough, the large trap will digest them as the small one.
