With so many different kinds of soil on planet earth, some soils are extremely nutritious for plants while others are not. Some plants, like the venus flytrap, have the dangerous ability to lure their prey into their trap or between their leaves for nutrition and supplementing the low concentration of nitrogen in their habitat. As the prey sits on the leaf, the four ‘trigger hairs’ on the leaf’s interior surface trigger the leaf to close. Thereafter, the plant digests it in 5 – 7 days after which the trap opens, and the outer shell of the prey is thrown out.
