Summertime and the living is easy...

The biological dynamics of thoughtless lifeforms may be 
somewhat understood by this experiment:  Into a five gallon 
fish tank place a dead mouse or any other type of unliving 
biological mass.

Notice that after a while mold forms upon the meat.

Bacteria appear and start feeding upon the mold.

Leave the lid off until you see flies in the tank, then 
place a tight fitting fine screen over the top.

During your screen lid fitting activity, most if not all the 
flies will take off and fly away.  No matter.  If they laid 
their eggs in any of their normally preferred moist areas, 
say, upon any open eye sockets or anal areas or any open 
wounds all will be well because that is where the bacteria 
are feeding upon the mold and the maggots (larval) are 
feeding upon the bacteria.

It is just a magnificent symphony of eternal murder; each 
eating the other as all in the sea and land do.

Fish are jumping and the cotton is high

Eventually, maggots will hatch and appear from the eggs that 
the flies laid and start feeding upon the bacteria in the 
dead biomass.

Assuming a nice comfy environment and a ten day born again 
(metamorphic) lifespan, the larva will give way to the born 
again flies, spreading their wings to dry and then starting 
to fly.

You spread your wings and head for the sky.

But the lid will be upon their small contained planet (the 
screen sealed terrarium) and they will not be able to 
escape.  They are obliged to remain in the aquarium turned 
terrarium.

With blind fecundity, the flies remain and lay their eggs.

The eggs hatch into being as worms (maggots) and then feed 
on the bacteria in the corpse in the terrarium.

And with blind fecundity their numbers increase until 
suddenly all the food is used up.

The sudden lack of food event in our little world occurs 
seemingly almost at once, as the migratory maggots with 
their incessant chomping, devour the bacteria who devoured 
the mold in the corpse down to its last sustaining morsel.

Then the mold disappears without decaying meat to feed on. 
Then the bacteria disappears without the mold to feed on. 
Then the maggots disappear without the bacteria to feed on. 

But there is a temporary respite.

The dead and dying maggots are used for food by the mold.
Then the bacteria have a last meal from the final mold.
And then a final maggot feeds itself upon the last of the 
final bacteria and may or may not survive to be reborn again 
as the "last fly".


                         Restated:

Then the maggots, now foodless, start to die off en masse.  

The early deaths of starving maggots provide some food for 
the survivors.

It takes ten dead maggots to feed one maggot until its born 
again as a fly.

Now the flies start to perish but they have laid their eggs 
in what is now sterile soil.

They perish quickly.

The population precipitously declines.

The remaining maggots now devour the dead flies.

But soon there is only one maggot (larva) left and if it 
makes it to its reborn again term, it too will be a fly.  

The final fly.

The last born again fly.

And then a little of the mold.

And then a little of the bacteria.

but no eggs hatch from the old 
dying born again final fly.

And then the mold dies.

And then the bacteria die

The hot desiccating sun

bakes what remains

in the terrarium

into a dusty crust of non-life.

And there it stays for months



finally a downpour fills

the terrarium half full

of water

The crust dissolves

and lifts up

from the bottom

when rains come


After a time

and in the

water from the heavens

comes a seeding rain

Hurricanes and typhoons

from distant lands

filling the terrarium

with water

and the most elemental 

living things
