1. Soil serves as a:
medium for plant growth,
regulator of water supplies,
recycler of raw materials,
habitat for soil organisms, and.
landscaping and engineering medium.
2. Soil organisms, which range in size from microscopic cells that digest decaying organic material to small mammals that live primarily on other soil organisms, play an important role in maintaining fertility, structure, drainage, and aeration of soil.
3. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
Answer : The correct Lewis-dot structure of nitrate ion is shown below and the nitrogen has 4 covalent bonds.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The number of valance electrons are shown by 'dot'.
The given molecule is, nitrate ion
As we know that nitrogen has '5' valence electrons and oxygen has '6' valence electron.
Therefore, the total number of valence electrons in 
= 5 + 3(6) + 1 = 24 electrons
According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
The correct Lewis-dot structure of nitrate ion is shown below.
You do not need the display of positive and negative charges.
The arrangement within energy levels of the seven electrons of an atom of nitrogen is 2.5 (that is the first sub shell= 2 while the second sub shell=5)
explanation
In every atom the first energy level can accommodate a maximum of two (2) electrons. The next energy level can accommodate a maximum of 8 electrons. Therefore the seven electron for nitrogen, 2 electron are put on first sub shell while other other 5 are putted in the second sub shell.
