The diagrams above showcase how the small and large venus fly traps actively absorb nutrients from trapped insects. This illustration shows the adaptations of plants that grow in arid and semi arid regions, where there is a deficit of plant nutrients in the soil.
Nitrogen deficiency in plants results in stunted growth and weak stems. to compensate this lack, canivorous plants such as the venus fly trap have adapted to the absence of nitrogen in the soil by feeding on insects.
They lure insects into their trap using a sweat scent within the trap which also has a colourful interior. The trap is equipped with trigger hair, whose purpose is sending a signal when an insect takes the bait. The trap seals shut,killing it instantly and digestive enzymes take over, breaking down the insect for nutrients absorption.
Notably, there is a difference in how the small venus fly trap and the larger one operate as represented in the diagram above. The smaller one takes a cosiderable amount of time to digest and absorb nutrients, whereas the larger one opens up almost immidiately for the next insect.
