The provided picture compares and contrasts the process by which Venus flytrap species optimize their digestive enzymes to capture and digest prey.
Generally speaking, both species follow a similar three-step hunting process, beginning with activating trigger hairs and ending with releasing digestive enzymes after capturing a suitable prey.
In the case of the smaller Venus flytrap, when the prey comes into contact with the trigger hairs on the trap, a signal is generated to activate the mechanism of closing the mouth of the tree, forming a sealed enclosure. Following this, digestive enzymes are secreted, gradually breaking down the prey. After absorbing all the nutrients from the digested prey, the trap will reopen to be ready for the next catch.
On the contrary, the large Venus flytrap works a little differently when it comes to capturing small insects. The initial stage is similar, when prey is detected after touching the plant’s sensors, causing the trap’s lobes to close. However, the larger gaps between the lobes and the spines prevent the trap from closing completely, and the prey is only loosely held. As a result, when the insect escapes, the trap opens again.
