Question

In the phosphorus cycle, phosphate becomes available by weathering of rocks first to
A. Consumers
B. Producers
C. Decomposers
D. None of these

Answer 1

Hint: The phosphorus cycle is a process in which the phosphorus moves through the different spheres of the biome which are the lithosphere, hydrosphere and biosphere. It is an important element for life. In nature the phosphorus is found commonly as the phosphate ions which are found in the sedimentary rocks, volcanic ashes, mineral dusts etc. the phosphorus has no real gas phase like carbon, nitrogen and sulfur.

Complete answer:
The phosphorus cycle takes place in three cycles which are the weathering, absorption of the plants, and the return of phosphorus to the ecosystem. In the first process weathering the phosphorus is found in nature in the form of phosphate ions, these are then available to the plants and the producers as they absorb the phosphate and use them to produce the biological molecules which are the nucleotides, nucleic acids etc. the phosphate is then circulated into the nature as the organic phosphorus transfers to other organisms.

Hence, the correct option is B.

Note: In phosphorus cycle, the weathering process makes phosphate available to the soil which are the consumers of phosphate. Phosphate is an important component of cellular and organic molecules. It also plays an important role for the transport of energy. They are found abundantly in nature, as the phosphorus cycle ensures that phosphorus is taken by the plants.
