Why do biologist not classify a car as a living organism?
because it is not living, not a livin organism. I would class it
as a thing, a materlier. But what does it mean to be alive?
According to biologists living organisms are characterized by seven
"signs of life": 1) living things have highly organized, complex
structures; 2) living things maintain a chemical composition that
is quite different from their surroundings; 3) living things have
the capacity to take in, transform, and use energy from the
environment; 4) living things can respond to stimuli; 5) living
things have the capacity to reproduce themselves; 6) living things
grow and develop; and 7) living things are well-suited to their
environment.
