Mammal Length and BMR, Body Mass and BMR - Coggle Diagram
Mammal Length and BMR, Body Mass and BMR
Abstract
Background
After reading about how age can sometimes be determined by BMR and other components that come into play, why not question more?
-
We are looking for relationships between the body masses of birds and mammals along with their BMRs. We are also looking for any relationship between body length and BMR of mammals.
-
Results
There is a relationship between birds and mammals in terms of body mass and BMR. The greater the body mass, the greater the BMR and vice versa.
There is also a relationship between the body length and BMR of mammals, the greater the body length, the greater the BMR.
Introduction
Background
BMR is something all organisms need to utilize their energy. This is the measure of metabolism when the organism is not exercising or exerting too much energy,
Much like we burn calories while sitting and sleeping, the same goes for other organisms.
Unknown/Problem
-
While body mass may have a relationship with BMR, does body length? Body mass and length aren't always related.
Question and Hypothesis
Is there a relationship between body length and BMR for mammals specifically? What about body mass and BMR in both mammals and birds?
The greater the body mass is, the greater the BMR is. The greater the body length, the greater the BMR is.
The more body mass an organism contains, the more it can metabolize. The longer an organism is usually indicates more surface area to contain more mass in, also leading to a greated BMR.
Approach
Research the species given in the Quaardvark database and see how the factors work out to show a relationship in both areas of questioning.
Methods
Design
Independent Variable: Body mass of each species, body length of each species tested
-
Subjects
Experiment groups: Mammals, birds
-
Procedure
Using the Quaardvark database and selecting specific physical qualities such as body mass, body length, and BMR. Assemble into charts according to hypothesis question.
Results
Paragraphs
Gain an understanding of just how important BMR can be and how it may be useful to understand the other components that may effect or be affected by such a factor.
Figures
Add in tables that came from Synopsis 5? Captions above tables, still explain in paragraphs what we're looking at and how it supports the hypotheses.
Discussion
1st paragraph, main findings
What does this relationship mean for mammals and birds? How are their lives changed by having determined BMRs?
Reiterate tying the tables in to support both hypotheses. BMR has a positive relationship with both body mass and length.
Middle paragraphs, other findings
Limitations of experiment: Species not included in the database, outliers that may not have the same representation, animal members that may be an outlier to the averages of their species' factors, species that may have different physical factors based on geographical locations.
Last paragraph
Tying all of the hypotheses together. BMR is something that we as humans experience and has a giant impact on day to day life. Exerting energy is part of daily functions, without proper storage of energy, there could be negative consequences.
