Soil is a mixture of minerals, living things,
water, air, etc. Soil is full of living organisms
which create a rich environment where plants
(which are also alive) can grow. You can find
worms and insects in soil, also fungi, and many
bugs. Some of these living things can not be seen
without a microscope, but they are there and they
are responsible for the well growing of plants.
Depending on the composition of the soil,
different plants can grow. There are different
kinds of soil, depending on how they are formed.
You may have noticed that some soils are almost
black, some are brown, etc. The plants that grow
on a certain soil are the ones that need the
specific ingredients on that soil.
