A) minerals
B) humus
C) litter
D) None of these
Correct Answer: B
Solution :
\[{{A}_{0}}\] region is just below the \[{{O}_{1}}\] region in soil, in which decomposition has begun. Thus, organic matter is found under different stages of decomposition and microorganisms like bacteria, fungi, Actinomycetes are frequently found. The decomposed matter is called humans. C-horizons are mineral horizons below the B- horizon but excluding true bedrock and without any characteristics of A or B horizons. It consists of incompletely weathered large masses of rocks. Litter is the waste matter deposited on land. Leaf litter is dead fallen leaves on land. It is present on the 0-horizon of soil.
