Corn
Corn is a tall plant with very long, green leaves. Caterpillars like to eat the leaves of corn plants. When caterpillars start to eat a corn plant’s leaves, the plant gives off a special smell. Humans can’t smell it, but wasps can. Wasps follow the smell to the plant. Wasps like to eat caterpillars, so wasps save the corn plant by eating up all the caterpillars.
Stinging Nettle
A stinging nettle plant has green leaves with points all around the edge. The leaves are covered with small hairs. Some of the hairs are short, and some are long and sharp. When animals try to eat this plant, the long, sharp hairs go into the animals’ skin. Each long hair is like a stinger. It stings the animal’s skin. Animals don’t want to eat this plant because they will get many small stings. People stay away from this plant because it will sting human skin, too!
