Answer:
Deposit red liquid in me.
Lovely and round, I shine with pale light. Grown in the darkness, a lady's delight. What am I?
I row quickly with four oars but never comes out from under my own roof.
I am essential to life on earth! I am split into thirds. Two thirds are the same. One of the thirds is 8. The other two are 1 each.
My first is a heir; My second's a snare; my whole is the offspring of fancy; which I sent out of play upon Valentine's day As a token of love to my Nancy.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
