The Riddle by Character Sarah Beth Stone age 10

In the field I stand, tall and grand
A sight to see across the land
I am a sparkling wave against the sun
but a mere blade when only one
I am home to birds it is very fun
but I have to perish to be home for some.
My golden hue shines in the sun
A symbol of life that has just begun
Birds make their nests within my strands
A home for them, I gladly stand
But to be their home, I must die
And in death, give life to the sky
My purpose is clear, to nourish and feed
To provide for all, is my great deed
And though I must perish, my legacy will live on
For I am the field of wheat, from which new life is born.
