The aquatic animal known as the crawfish has become well-known in the scientific community due to its common use in a lab or the natural field. While some of its species are known for their invasiveness and “affect [on the] fundamental aspects of aquatic systems like water quality” (Pearl), the crawfish has provided insight into various fields of science because of its ability to be easily manipulated. This small animal has been utilized by many researchers studying the origins of the animal’s own energy source in plant detritus (Garzoli et al., 2014, p. 47) to simply measuring the effects of it on freshwater ecosystems (Pearl, Adams, & McCreary, 2013, p. 171). The use of the crawfish has even stemmed into experiments related to humans, as seen where it was the test subject for aerobic respiration, the process of taking in oxygen and producing carbon dioxide. This aquatic animal, since it undergoes aerobic respiration, was used to test the hypothesis that lower temperatures causes a slower exhalation rate and therefore requiring a higher level of titrant to help the solution, in which the crawfish was placed, reach equilibrium. Titration is the process of adding one solution to another solution to counteract a reaction. This was useful to gain results from the experiment to draw valid conclusions.
Respiration, by a definition, is a “series of coupled oxidation and reduction reactions that result in the transfer of electrons from an appropriate electron donor to an…
