Select one abiotic factor that was monitored, either water clarity or dissolved oxygen level, and
create a line graph showing the measurement of the abiotic factor over time. Then select one
biotic factor that was monitored, either coral coverage, juvenile parrotfish, or mature parrotfish,
and create a line graph showing the measurement of the biotic factor over time.

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.
