The correct answer is option 1, Utricularia. Utricularia is an example of an insectivorous plant. Insectivorous plants are plants that obtain nutrients by trapping and consuming small insects. Utricularia, also known as the bladderwort, has small bladder-like structures on its leaves that have a trap mechanism. When small insects come into contact with triggered hairs on the bladder, the trap door opens, and the insect is sucked into the bladder. The plant then secretes digestive enzymes to break down the insect and absorb the nutrients. This adaptation allows the Utricularia to supplement its nutrient intake, especially in nutrient-poor environments like bogs and marshes. The other options, Sequoia Gigantia, Nostoc, and Bryophyta, are not insectivorous plants.
