Noticeable effect on germination rate of the radish seeds

3. Was there any noticeable effect on the germination rate of the radish seeds as a result of the pH? Compare and contrast the growth rate for the control with the alkaline and acidic solutions.
4. Based on your results would you say that the radish has a broad pH tolerance? Why or why not? Use your data to support your answer.
5. Knowing that acid rain has a pH of 2-3 would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?

1. What is the % concentration of oil in the first, second, and third trophic levels in our food chain?
2. How did the concentration of oil change from one trophic level to the next?
3. How does the change in concentration represent biomagnification?
4. How does this also illustrate the amount of energy transferred from one trophic level to the next?
