Organic

Organic typically refers to any form of matter that has a biological origin. In other words, it came from or it is (or was) a life form.

It should be noted however that not all life forms can be considered organic, as there are forms of life that are inorganic, such as the Lava Men, Dryads and Rock Men, all of which are living beings, but they are made of material that is inorganic, namely rock-like matter.
