Umuc biology 102/103 lab 7: ecological interactions

This contains 100% reform embodied for UMUC Biology 103 LAB07: Ecological Interactions. However, this is an Retort Key, which resources, you should put it in your own suffrage. Here are the questions that accomplish be retorted. Attached is the lab that is easily completed. Enjoy!


Pre-Lab Questions

1.    Would you look-for endangered cast to be further regularly generalists or specialists? Explain your retort.


2.    How does latitude assume breathe-into availability in an ecosystem?


3.    Choose a cast and relate some adaptations that cast exposed that assign them to outlast in their artless habitat.


Experiment 1: Effects of pH on Radish Seed Germination

Data Tables and Post-Lab Assessment

Table 1: pH and Radish Seed Germination

Stage/Day Observations




Initial pH




1 (0400hrs)




2 (0400hrs)




3 (0400hrs)




4 (0400hrs)




5 (0400hrs)




6 (0400hrs)




7 (0400hrs)








Post-Lab Questions

1.    Compare and form a continuity graph invetereprimand on the postulates from Table 1 in the boundlessness adown. Place the day on the x axis, and the enumereprimand of seeds germinated on the y axis. Be confident to include a address, label the x and y axes, and procure a myth describing which continuity corresponds to each compound (e.g., blue-colored-colored = acetic severe, green = sodium bicarbonate, etc…).



2.    Was there any noticeable chattels on the germination reprimand of the radish seeds as a remainder of the pH? Compare and contrariety the augmentation reprimand for the administer after a while the alkacontinuity and severeic solutions.


3.    According to your remainders would you say that the radish has a coarse pH tolerance? Why or why not? Use your postulates to buttress your retort.



4.    Knowing that severe rain has a pH of 2 - 3 would you finish that fruit cast after a while a cramped tarnish pH dispose are in sorrow? Explain why, or why not, using philosophical rationalistic. Is severe rain a collection for introduce cast and fruits?








5.    Research and briefly relate a legitimate earth pattern environing how severe rain assume introduces. Be confident to demonstreprimand how pH contributes to the termination, and contemplated solutions (if any). Descriptions should be approximately 2 - 3 paragraphs. Include at meanest three citations (use APA formatting).
