Spring
In spring everyone wakes up those in the topsoil uncurl themselves and move down to the subsoil and join others there who are waking up from their winter sleep.
Together they start moving up through the roots - into the trunk and steadily up through the branches
to form tiny new baby leaves
Momentum is building up
for the rush of summer

Summer
In Summer activity is frantic - Everyone is awake and full of energy
The new leaves made in spring grow quickly
Movement from the topsoil to the subsoil is hurried
as they join long queues waiting impatiently to get into the roots
movement up though the trunk and the branches is fast and excited
The leaves on the branches quickly reach maturity

Autumn
In Autumn the mature leaves of summer turn colour and begin to fall
They join those already in the topsoil and begin settling themselves into place for winter
Movement from the topsoilis slow - almost stopped
Nearly all energy is spent.
Most of those in the subsoil
are getting ready to sleep
while the few entering the roots and those already in the trunk and the branches are preparing for winter
There is little movement
except for leaves falling.....

Winter
Winter - All the branches are bare
The leaves which fell in Autumn have settled into the topsoil
the subsoil is asleep
All movement has stopped
Those in the roots, trunk and branches prepare for the long cold winter
by wrapping their arms around themselves and huddling together
Everyone waits for Spring
