In a typical soil,

Quizplus · Accepted Answer

The topsoil tends to lose mineral nutrients by leaching, which means that water dissolves and carries the nutrients down to lower layers of the soil.

Answer: D
 The dead and decaying organic matter accumulates in the B horizon, which is also known as the subsoil.

Answers B, C, and E are incorrect because:

B) There are typically three horizons in a typical soil: topsoil, subsoil, and bedrock.
C) The C horizon consists primarily of weathered rock fragments and does not typically contain significant amounts of organic matter or loam.
E) More clay in the soil means there is less air space for oxygen to penetrate, which can lead to reduced root growth and oxygen availability for microorganisms in the soil.
