The image compares two sets of steps between how a small and a large plant called Venus Flytrap make use of their digestive enzymes to catch prey.
The small trap performs some steps in a more attacking approach. When an insect crawls gradually to the center of the plant, it activates some trigger hairs to prevent the prey from escaping. After the prey gets trapped, two sides of the trap snap shut like closing doors, making sure the insect has no chance of getting away. Meanwhile, the plant releases a substance called digestive enzymes to break down nutrition from the prey’s body. The nutrition is then absorbed completely while the prey gets stuck in the trap.
On the contrary, due to the size difference, there was a lack of inefficiency in the way a large trap handles a small prey. When the prey scorches towards the Venus Flytrap, it repeats the same action of triggering hairs to set a trap to the prey. But when the trap snaps shut, as the process of closing in larger size happens more slowly, the prey easily finds a way out. After failing at capturing the food it needs, the trap snaps opened again.
To summarize, both processes have three steps, starting from catching the prey. However, the results are different: the large trap is unable to utilize digestive enzymes as the size creates limitations in subduing the prey compared to the small one.
