Earthworms don’t have bony bits
and so they’re called invertebrates.
There’s billions living in the soil
that burrow, stretch, contract and coil.
Creating holes within soil’s layer
can mix it up and add some air
which helps break-down organic waste
and drain the rain in record haste.
Organic matter, we conclude
provides the worms with all their food.
Consuming soil is what they do.
Excreting lots of earthworm poo.
These squiggly clumps of mud have passed
through worm’s insides. They’re called a cast.
Those casts make soil a better place
so plants grow at a faster pace.
Without the worms, the soil would not
stay very clean and start to rot.
The earthworms all have key careers
as eco-system engineers.
