THREE RHYMING RIDDLES

1)
My first is in ocean, but not in sea,
My second in wasp, but not in bee;
My third in glider and also in flight,
My whole a creature that comes out at night.

2)
My first is in window, but not in pane,
My second in road, but not in lane;
My third is in oval, but not in round,
My fourth in hearing, but not in sound.
My whole a sign of peace,
From the Ark won quick release.

3)
My first is in fish and also chips,
My second in mouth, but not in lips;
My third is in ache, but not in pain,
My fourth is my third all over again.
My fifth is in pupil, but not in class,
My whole a beast that feeds on grass.
