Answer:
In addition to dinitrogen, other inorganic and organic forms exist in the soil as well.  It makes up 78 percent of the atmosphere but <u>cannot be used by plants. </u>It is taken into the soil by bacteria, some algae, lightning, and other means.

3, 1, 2, 5, 4. :-) I hope this helped. DNA is the smallest and the atmosphere is the largest.
 
        
             
        
        
        
The correct answer is (b.) infiltration. Rainfall is to precipitation as groundwater is to infiltration. Precipitation is the release of the water from the cloud (evaporated water) in the form of rain and snow. Infiltration is a process in which the water from the ground enters the soil.
        
                    
             
        
        
        
Answer:
Percent error = 8.3%
Explanation:
Given data:
Accepted value of specific gravity = 7.2
Measured value of specific gravity =  7.8
Percent error = ?
Solution:
Percent error = measured value - accepted value / accepted value × 100
Now we will put the values in formula.
Percent error = 7.8 - 7.2/7.2 × 100
Percent error = 0.6/7.2 × 100
Percent error = 0.083 × 100
Percent error = 8.3%
