Which is more dead?

I was walking and singing to myself about grass.  You see, grass is an amazing plant.  Chop it down--it grows.  Walk on it--it grows.  Tread it down into the mud--it still grows.  It spreads itself over the earth and holds the soil together.  It makes life a bit cooler and prettier where it grows.

Well, around this dorm is all this dead grass that was laid out to shelter the new grass that was planted.  Some of that new grass is coming up and that is what started the song.  Then as I walked, I came across these patches of dead grass standing upright.  The grass is yellow and dry, and no green grass is growing in the midst of it.  So I wondered, which is more dead--the dead grass standing up or the dead grass lying down? 

Which is more dead, the dead still standing or the dead who have fallen?
