Animals depend on cerain traits for their survival. It can range from mimicry, like a fly that looks like a honey bee, to self-defense, like the skunk and its spray, to catching food, like a cheetah's speed to outrun its prey. Animals can sometimes even help humans in their quest to help perserve our planet. For example: Did you know that since bamboo is very hard to digest, pandas have a special bacteria in their digestive system, called microbes, that turns plants into energy? Undertanding a skill like this can help scientist to elude pollutions emmited by automobiles and help stop global warming.
