Which nutrient tends to cycle within a single ecosystem?
A. phosphorous
B. water
C. nitrogen
D. carbon
Answer (2)
In ecosystems, phosphorous is a nutrient that tends to cycle primarily within a single ecosystem, unlike nitrogen and carbon, which are more globally circulated. It is essential for plant growth and moves through food webs with limited interaction beyond its starting ecosystem. Its cycling occurs through processes like plant uptake, consumption, and decomposition. ;
The nutrient that tends to cycle primarily within a single ecosystem is phosphorous. This nutrient is absorbed by plants, consumed by animals, and returned to the soil through decomposition, making its cycle more localized than those of nitrogen or carbon. Thus, the correct answer is A. phosphorous.
