4. Are bacteria bad
usually think that bacteria are dangerous. We wash our hands and
use antibacterial soap to kill bacteria that can make you sick.
Although there are bad bacteria that make you sick, most bacteria are
good for us and we need them. You have bacteria in your intestines to
break down food. Yogurt, which is a healthy snack food, is
made with bacteria. We could not exist without bacteria!
bacteria are decomposers, so they break down all the dead material.
They are the reason the Earth isn't covered with dead dinosaur bodies.
