o cheiro da relva acabadinha de cortar...

"The next time you’re enjoying the fragrance of freshly mowed grass, remember that you’re actually smelling the distress call of all of those individual plants.

A group of scientists were studying wild tobacco plants when they noticed a caterpillar eating some of the leaves. Shortly after, a predatory insect came to eat the caterpillar. The scientists eventually determined that the predatory plant responded to the odor of cut leaf and came to find the caterpillar responsible for eating it. While some plants develop a natural pesticide to keep pests away, this adaptation is pretty brilliant. It allows the plant to have protection against predators without allowing the predators develop resistance to a pesticide."
