Environmental scientists investigated the bioremediation of crude oil-contaminated soil using a specialized bacterial consortium. Table 1 shows the measured soil moisture content and temperature at four distinct monitoring sites (Site 1, Site 2, Site 3, and Site 4).
Table 1: Soil Characteristics at Monitoring Sites
| Monitoring Site | Soil Moisture Content (%) | Soil Temperature (°C) |
|---|---|---|
| Site 1 | 15 | 25 |
| Site 2 | 30 | 35 |
| Site 3 | 45 | 15 |
| Site 4 | 60 | 25 |
Table 2 displays the hydrocarbon degradation rate by the bacterial consortium measured across various soil moisture contents and incubation temperatures in laboratory testing.
Table 2: Hydrocarbon Degradation Rate (mg/kg/day)
| Incubation Temperature (°C) | 15% Moisture | 30% Moisture | 45% Moisture | 60% Moisture |
|---|---|---|---|---|
| 15 | 10 | 25 | 40 | 20 |
| 25 | 30 | 65 | 85 | 50 |
| 35 | 15 | 35 | 55 | 30 |
Based on Table 1 and Table 2, rank the four monitoring sites in order from the site with the HIGHEST estimated hydrocarbon degradation rate to the site with the LOWEST estimated hydrocarbon degradation rate.

- 2Site 3
- 3Site 2
- 4Site 1
Cevap
Site 4, Site 3, Site 2, Site 1
To rank the sites from highest to lowest degradation rate, combine the site parameters from Table 1 with the degradation rate values in Table 2. Site 4 (60% moisture at 25°C) yields 50 mg/kg/day. Site 3 (45% moisture at 15°C) yields 40 mg/kg/day. Site 2 (30% moisture at 35°C) yields 35 mg/kg/day. Site 1 (15% moisture at 25°C) yields 30 mg/kg/day. Ordering these values from highest to lowest gives Site 4, Site 3, Site 2, and Site 1.
