Soil microorganisms are the unsung engineers of terrestrial ecosystems. A single teaspoon of healthy topsoil harbors billions of bacteria, fungi, protozoa, and nematodes. These microscopic entities decompose fallen foliage, cycle essential nitrogen and phosphorus, and build soil aggregate structure. ---- When fields are subjected to excessive chemical pesticides and intensive mechanical tillage, these fragile subterranean webs collapse, turning fertile ground into barren dirt.

Doğru cevap: A) Without their unceasing metabolic activity, higher plant life would quickly starve for essential nutrients.
Çözüm: Toprak mikroorganizmalarının besin döngüsü ve bitkileri besleme işlevi anlatılmış; boşluktan sonra da onların yok edilmesiyle toprağın verimsizleşeceği söylenmiştir. A seçeneğindeki "Without their unceasing metabolic activity, higher plant life would quickly starve for essential nutrients" cümlesi bu hayati rolü kusursuz tamamlar.
