1.	Which one of the following is the simplified sequence of phosphorus cycling in a terrestrial ecosystem?(a) Soil → Producers → Rock minerals → Consumers → Decomposers(b) Rock minerals → Soil → Producers → Consumers → Decomposers(c) Rock minerals → Decomposers → Producers → Consumers(d) Decomposers → Rock minerals → Consumers → ProducersThis question was posed to me in final exam.I would like to ask this question from Ecosystem topic in portion Ecosystem of Biology – Class 12
Answer» Correct option is (B) ROCK minerals → Soil → Producers → Consumers → DECOMPOSERS Easiest explanation: The phosphorous CYCLE starts with rock materials and ends with the decomposers. The phosphorous enters the ecosystem through rock minerals and, there is a negligible exchange of gaseous PHOSPHORUS between organism and environment.
