Science Assignment Question

Can you help me understand this Science question?

Assignment:

1. Briefly describe the major processes and components of the water cycle. You can use Figure 3.15 in your text to help you out. (10)

2. Calculating Daily Water Use (DWU)

a. In the data table below, Joe Smith’s water usage for five days has been recorded in gallons. The water usage is categorized by the type of water use ranging from “take a shower” to “washing clothes”. Values are in gallons of water used. Calculate Joe Smith’s Total Water Usage first adding up usage data down by category into the daily subtotal cell relative to each column and across, by row, into the subtotal by activity. Total subtotals across and subtotal down into the bottom right cell. As a check the sum of the Daily subtotals and the Activity Subtotals should equal each other. (2)

Daily Subtotal (gallons)

Total Water Usage:

(gallons)

3. Calculate the Daily Water Usage (DWU) by taking the total gallons consumed and divided this number by the number of days the experiment took place. In this case 5 (May 5 to May 9). Joe’s DWU = _____________ (1)

4. Which of Joe Smith’s activities consumed the most water? Is this typical for the average American? (2)

5. Do you think Joe Smith’s DWU was high or low? Use and cite at least one outside source to support your opinion on this question. (3)

6. In what ways do you think he could conserve his water usage? (2)

Nutrient Cycles:

7. Briefly describe the major processes and components of the carbon cycle. You can use Figure 3.17 in your text to help you out. (10)

8. Briefly describe the major processes and components of the nitrogen cycle. You can use Figure 3.18 in your text to help you out. (10)

9. Briefly describe the major processes and components of the phosphorus cycle. You can use Figure 3.19 in your text to help you out. (10)

10. Find an article on the internet from the past 3 years that describes a way in which a human activity disrupted one of the 4 cycles above. Which processes were disrupted? What are/were the consequences of this disruption? How could the disruption be mitigated? Link and cite the article using APA formatting guidelines. (40)
