Dried grass clippings mixed into garden soil gradually decompose, providing nutrients for beneficial soil bacteria. This results in better-than-average plant growth. Yet mixing fresh grass clippings into garden soil usually causes poorer than-average plant growth.
Which one of the following, if true, most helps to explain the difference in plant growth described above?OPTIONS
[A]. The number of beneficial soil bacteria increases whenever any kind of plant material is mixed into garden soil.
[B]. Nutrients released by dried grass clippings are immediately available to beneficial soil bacteria.
[C]. Some dried grass clippings retain nutrients originally derived from commercial lawn fertilizers, and thus provide additional enrichment to the soil.
[D]. Fresh grass clippings mixed into soil decompose rapidly, generating high levels of heat that kill beneficial soil bacteria.
[E]. When a mix of fresh and dried grass clippings is mixed into garden soil, plant growth often decreases.
