Here are the results of the changes in measurements:
Worm tank before - Total = 15cm; leaf layer = 25cm; compost layer = 17cm; soil layer = 5cm.
Worm tank after - Total = 15cm; leaf layer = 15m; compost layer = 9.5 cm; soil layer = 5.3cm.
Anti-worm before: Total = 26cm; leaf layer = 26cm; compost layer = 19cm; soil layer = 5cm.
Anti-worm after: Total = 19cm; leaf layer = 19cm; compost layer = 15cm; soil layer = 5cm.
Questions:
1. What differences can be easily seen between the two tanks?
-the height of the soil, leaf and the compost got lower, that means that the leaf and the other stuff got decomposed.
2. Is this the result you expected?
-yes this was the result we expected. we have expected that the height of the worm tank will get lower and the result was correct to what we have expected.
3. Why did the soil layer get bigger in the worm tank but not in the anti-worm tank?
-i think it's because the leaf and compost got mixed up with the soils. leafs matter didn't changed but only the shape have changed, so the leaf and compost is the part of the soil.
4. In the worm tank, why did the compost layer get much smaller, but the soil layer only got slightly bigger?
-the compost got decomposed and the compost layer got changed to the different layer, so the layer of the compost got smaller but the layer of the soil got bigger.
5. Why do you think the leaf layer remained much the same in both tanks (why didn’t it change much)?
-the leaf couldn't get decomposed because the layer of the compost were getting decomposed first.
6. Even though there were no worms in the anti-worm tank, the compost layer still got a bit smaller. Can you suggest a reason for this?
-i think it's composed of the ant and other bacteria in the tank. that decomposer had decomposed.

DEAR SCIENCE-AHOLIC,
THANKS FOR ANSWERING THE QUESTIONS. YOUR ANSWERS ARE PRETTY GENERAL THOUGH. MORE INFORMATION WOULD BE HELPFUL. I'VE ANSWERED BELOW IN CAPS.

DO THE LEAVES LOOK VERY DECOMPOSED? THE COMPOST IS WHAT HAS OBVIOUSLY DECOMPOSED.
2. Is this the result you expected?
-yes this was the result we expected. we have expected that the height of the worm tank will get lower and the result was correct to what we have expected.
WHY?

HOW DID THAT HAPPEN?
4. In the worm tank, why did the compost layer get much smaller, but the soil layer only got slightly bigger?

WHAT DID THE COMPOST LAYER GET CHANGED INTO? HOW DID THAT HAPPEN?
5. Why do you think the leaf layer remained much the same in both tanks (why didn’t it change much)?
-the leaf couldn't get decomposed because the layer of the compost were getting decomposed first.
WHY WAS THE COMPOST DECOMPOSING FIRST?

OK.
