Materials
Use the Quaardvark generator to get the data of the mammals by putting the criteria that is needed. Use the data that was collected and and input it into excel to get the necessary line chart, statistical test and bar graph from the statistical test.
Procedures
Using the Quaardvark generator collect the metabolic rate and lifespan of captive mammals and the metabolic rate and lifespan of wild mammals. Put the data given into an excel spreadsheet. Using the data collected graph it into a line chart. The graphs need to be appropriate for a science research paper. Therefore, a trendline needs to be added. This is done by right clicking the points from the line chart. Select "add trendline" on the pop up menu. "Format trendline" will appear on the right-handed side of the screen. Linear Trendline is the default. As well, select the following two boxes at the bottom of the format trendline menu; Display Equation on chart and Display R-squared value on chart.
Design
The independent variable is the metabolic rate of the captivated and wild mammals. The dependent variable is the lifespan of the mammals. The control is the group of animals that are being tested which are mammals. The treatment groups are mammals.
INTRODUCTION
Unknown problem
Some unknown questions are what relations do mammals and bird have when it comes to their BMR, mass-specific mass and body mass. Also, do those factors affect each species. This hypothesis is being tested to understand about the mammals body mass, BMR and mass-specific mass
Question & hypothesis
The questions that is being asked is does the metabolic rate of a captivated mammal and a wild mammal affect their lifespan? My hypothesis is that captivated mammals will have a larger BMR and therefore will have a longer lifespan than wild mammals.
Approach
The questions that is being asked is does the metabolic rate of a captivated mammal and a wild mammal affect their lifespan? My hypothesis is that captivated mammals will have a larger BMR and therefore will have a longer lifespan than wild mammals. I believe the data will prove this hypothesis correct because captivated mammals are taken care of, they are fed and protected from predators. As a result, they will always be resting and will need more calories to keep their body functioning while they rest. While as wild mammals are resting less because they need to go find their food or keep away from predators. Therefore, I predict captivated mammals will have a larger BMR and because they have a larger BMR they will have a longer lifespan than wild mammals.
Background
Metabolic scaling has been confusing scientist because of how different the variations they have seen. Therefore, the metabolic-level hypothesis explains the reason as to why theres such a big variation in the metabolic scaling. The metabolic-level hypothesis states that the metabolic rate should be closed to 2/3 when the animal is affected by limitation of resources and when the metabolic rate is closed to 1 when the animal is affected by its body mass constraints. In other words, the reason why the metabolic scaling has a large variation due to the fact that there's multiple different reasons that it could be affected.
ABSTRACT
Methods
The animals that were used were mammals and birds. The type of experiment used was a natural experiment.
Results
The slope for the relationship between the body mass and the basal metabolic rate in mammals was 0.0007.The slope for the relationship between the body mass and the basal metabolic rate in birds was 0.0031. The slope for the relationship between mass-specific body mass and BMR in mammals was 0.0244x-0.331. The slope for the relationship between mass-specific body mass and BMR in birds was 0.0395x-0.352. Mammals had a 11185.24g body average while birds had a 305.30g body average. The bird BMR average is 1.29 W while the mammals had a BMR average of 10.12 W. The average mass-specific BMR for birds is 0.019W/g while the average mass-specific BMR for mammals is 0.0051W/g.
Background
What is already known is that the metabolic-level hypothesis states that the metabolic rate should be closed to 2/3 when the animal is affected by limitation of resources and when the metabolic rate is closed to 1 when the animal is affected by its body mass constraints.The hypothesis that is the relationship of mammals and birds boy mass, mass-specific mass and basal metabolic rate.
DISCUSSION
Middle paragraphs
The relationship between body mass and BMR in mammals had a linear relationship which had a slope of 0.0007, the larger the body mass (g) the larger the increase in BMR (Watts). Limitations were that there were only

1st paragraph
The results from the line chart exhibits that captivated and wild mammals have very similar results. Therefore, the captivated mammals didn't live longer than wild mammals. Both they also had a similar slope, line chart of captivated mammals had a slope of 0.0338x + 11.826 while the line chart of wild mammals had a slope of 0.0252x + 9.1107.
RESULTS
Paragraphs
There's a myth that the more something is used that faster is will wear out (Speakman 2005). That same idea is used with animals. The more energy they use the less lifespan they will have. The line chart of captivated mammals had a slope of 0.0338x + 11.826 while the wild mammals line chart had a slope of 0.0252x + 9.1107.
