Answer :

Let's break down the process of finding the average number of plants at Site 2 for both samples (2010 and 2012) step-by-step.

1. Identify the number of plants at Site 2 in the years specified:
- In 2010, there were 112 plants.
- In 2012, there were 120 plants.

2. Calculate the total number of plants from both years:
- Add the number of plants from 2010 and 2012.
[tex]\[ 112 \text{ (plants in 2010)} + 120 \text{ (plants in 2012)} = 232 \text{ plants}. \][/tex]

3. Find the number of years over which the average is to be calculated:
- In this case, there are 2 years (2010 and 2012).

4. Calculate the average number of plants:
- Divide the total number of plants by the number of years.
[tex]\[ \frac{232 \text{ plants}}{2 \text{ years}} = 116 \text{ plants/year}. \][/tex]

Therefore, the average number of plants at Site 2 for both samples is:
[tex]\[ \boxed{116} \][/tex]
