What i know about living things.

Living things are much more complicated than you might think they are. There are many ways to identify living things. Currently i know a couple things about identifying a living thing. For instance, each living thing must excrete waste. Each living thing must die, and it must change. I would like to find out other qualifications for living things. I would also like to learn about what living things can be other than animals. Hopefully, i will be able to learn about them.
