Life - Wikipedia, the free encyclopedia

Life - Wikipedia, the free encyclopedia:

"Life (cf. biota) is a characteristic that distinguishes objects that have signaling and self-sustaining processes from those that do not,[1][2] either because such functions have ceased (death), or else because they lack such functions and are classified as inanimate.[3][4] Biology is the science concerned with the study of life."
