Question
metabolic rates and the carbon cycle
Need help figuring out an introduction for my lab report as well as a conclusion. All information for conclusion is below.
Need a conclusion from the data from the table and these questions w/ answers to be somehow put into the conclusion.
1. Which of your experiment beakers had the largest amount of carbon dioxide present in it at the end and why?
Answer: crawfishin bath of 28°C water
2. IS metabolic rate related to the size and temperature of an organism's body?
Answer: yes, give examples
3. was there less carbon dioxide in the experiment beaker that contained your organism and a plant than the experimental beaker that contained just an organism? why would you expect that to be the case?
Answer: yes because the CO2 is being taken in by the plant whereas no CO2 is being taken in crawfish alone.
4. why would there be a difference in the amount of carbon dioxide present in the beakers containing a plant kept in the light and a plant kept in the dark? Did you find a difference in your own experiment?
Answer: In Dark. Conssuming less CO2 for photosynesis
5. What factors may have led to errors in your determining metabolic rates and carbon dioxide levels? how confident are you in your results?
Answer: Not having beakers sealed all the way,measurements could've been wrong, size of crawfish.
and yes i was confident in my results.
From all that information i need help creating a conclusion for my lab report. Please help out. Also for the second question i would appriciate an example or two to be given.
Explanation / Answer
2. Metabolic rate is related to the size and temperature of the body. If the temperature is high, metabilic rate is high, the smaller the organsm, the heigher the metabolic rate. Eg: The metabolic rate of rats (almost 10 times) is very high than humans.
3. CO2 is less in beaker with organism and plant becuase CO2 is consumed by palnt, another beaker do not have plant, CO2 is high.
4. CO2, light and water are the most important ingredients of photosynthesis. If there is no availability of light, no photosynthesis occure, no CO2 is consumed.
From this experiment, we can conclude that, plants need light for photosynthesis and they consume CO2 during photosynthesis. Whereas the organisms (crawfish) release carbon dioxide by metabolic processes. The rate of metabolism depends on size and temperature. The higher the temperature, the more is metabolism; the smaller the body weight, the higher is metabolic rate.
