The United States, for example, exports some ____ million tons of grain per year - grain that contains large quantities of basic plant nutrients: nitrogen, phosphorus, and potassium. The ongoing export of these nutrients would slowly drain the inherent fertility from U.S. cropland if the nutrients were not replaced. THINK ABOUT IT! Another reason to know the nitrogen cycle!
- A.

- B.
20
- C.
50
- D.
10
- E.
240
Correct Answer
A. 80Explanation
The correct answer is 80. The statement mentions that the United States exports some million tons of grain per year, and this grain contains large quantities of basic plant nutrients such as nitrogen, phosphorus, and potassium. It then states that if these nutrients were not replaced, the ongoing export would slowly drain the inherent fertility from U.S. cropland. This suggests that the amount of grain exported should be high enough to cause this drain, and out of the given options, 80 million tons seems like the most plausible quantity.Rate this question:

Much more energy is used to ______ and prepare food in the home than is used to produce it in the first place.
- A.
Refrigerate
- B.
Prep
- C.
Cook
- D.
Transport
Correct Answer
A. RefrigerateExplanation
Refrigerating and preparing food in the home requires more energy compared to the energy used in producing it initially. This is because refrigeration involves maintaining a consistently low temperature, which requires continuous energy consumption. Additionally, the process of preparing food, such as chopping, peeling, and cleaning, also requires energy. On the other hand, the energy used in transportation and cooking is relatively lower in comparison.Rate this question:
