(Definitions
are in language suitable for the age of person most likely to be learning the
word. Accordingly, the definitions of simpler words may be oversimplified, with
exceptions ignored.)
The
most basic terms of all:
Animal – An alive creature
that eats other alive things. Most animals move around to find things to eat,
but some (especially ones that live in water) stay in one place and wait for
food to come to them.
Plant – An alive thing that
makes its own food from stuff it gets out of the air and ground. Plants are
usually green and grow out of the ground. They don't move from place to place
on their own, and only a few eat things. Grass and trees are plants. Trees
usually grow quite large, with leaves that grow from hard wood branches growing
out of a hard wood stem called a trunk.
