Snail And Gold Fish Lab Report

Carbon Dioxide Understanding and Production in Elodea, Snail, and Goldfish
Introduction
This report discusses an experiment to study the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant), Snail, and Goldfish, by measuring carbon dioxide production. Because ectothermic organisms (Elodea, snail, and goldfish) were placed in completely covered beaker, each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms, and to determine and compare the rate of cellular respiration in each organism. Aerobic respiration is the process which body obtains energy by using glucose + oxygen; this reaction takes place in mitochondrion in a cell; And the result of the reaction are carbon dioxide, water, and energy in the form of ATP ( adenosine triphosphate) (Hoefnagels, 2012). According to Biology 6th Edition, plants use light to convert atmospheric carbon (CO2) into carbohydrate (Johnson, 204). So I predicted snail would respire at the fastest rate and produce more CO2 because its weight was heavier than other two
We weighted each organism in order to compare similar weight organisms because if we compare elephant and mouse clearly elephant would produce more CO2 than mouse. Hypothesis found to be false because snail was dead, that’s why snail didn’t produce CO2. Elodea is a plant therefore it undergoes photosynthesis. The process of photosynthesis utilizes CO2. (C H O + CO O + H O + energy ). Since aerobic respiration produces CO2 as a byproduct, goldfish produced more CO2 than Elodea because they undergo aerobic respiration plus Elodea uses CO2.Next time if I do the experiment again, I would pick live snail so that I can compare goldfish and snail CO2
