In which way does the composition of soil, an abiotic factor, rely on living things? Bacteria break down dead matter and wastes, releasing nutrients into the soil.
Bacteria erode rocks into smaller particles that are added to the soil.
Insects make small tunnels in the soil Bacteria use these tunnels to break down dead matter.
Insects take in air and minerals and release these materials into the soil as wastes

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f. 

Hello,#agreed with joseph002.i got my source also from  source: hope this
