What was discovered in the area around us?

This past week we went on another nature walk and found a variety of different organisms.  We dug up a certain spot in a dark area below a group of trees.  In the sample we dug up we found:
- eighteen dead oak leaves and one that was still somewhat alive and green.
- There was a large amount of moss amongst a very large amount of dirt with some roots mixed in with both of them.
- There were six small twigs and one small woody plant with small green leaves.
- There were two broken acorns and six dead pine needles. The only animal we found was one black ant, Tobias.
All of these things we found were evidence of what  area we were in, which was a deciduous forest.
