The slow rate of decomposition of fallen logs in nature is due to their
Correct answer: C. Low moisture content
- A. The anaerobic environment around them
- B. Low cellulose content
- C. Low moisture content
- D. Poor nitrogen content.
Explanation
The microorganisms break down the complex compounds of dead protoplasm of producers and consumers absorb some of the decomposition products and release simple substances. The slow rate of decomposition of fallen logs in nature is due to their low moisture content. The cellulose is in high amounts in fallen logs. The environment around the fallen logs is aerobic. Decomposition rates are low under very wet or very dry conditions. Decomposition rates are highest in damp, moist conditions with adequate levels of oxygen. Wet soils tend to become deficient in oxygen (this is especially true in wetlands), which slows microbial growth.

About Man and His Environment
Ecosystems include biotic and abiotic components, food chains and webs, energy flow, nutrient cycles, populations and ecological relationships. Pollution and conservation cover air, water, soil and noise pollution, their effects on organisms, biodiversity loss, protected areas, sustainable resource use and methods for reducing environmental damage.
