A. O

B. A

C. B

D. C

3. True or false: In the outline find your section on soil horizons. In it you will find a diagram representing a view of a soil cut away. Horizon B in this example would be very difficult for soil organisms to move through because it would be a very hard layer.

Cody Gaines · Answer 1

1. the answer is O. It is the top layer of a soil profile with roots, fungi small insects etc.

2. The answer is A. In fact the correct answer should be upper part of A horizon, because the lower part contains much less amount of organic matter, but it suffers maximum leaching.

3. True; The B horizon is actually a zone of the deposition of leached material from A horizon and contains fine clay or silt. therefore it is difficult for any organism to penetrate it.
