I don't know no I literally had the same freaking question
Answer:
in a wide area where the is nothing but just grass
Considering the available options, the process used to calculate this statistic includes "<u>Averaging the fertility rate for the past 100 years."</u>
<h3>The other processes that were used to calculate this statistic are:</h3>
- Dividing the crude birth rate by the sex ratio
- Subtracting the crude death rate from the crude birth rate
Given that the data derived is in percentage, with a lower single digit, and one result showing negative. This implies there must be mean, division, and subtraction in the process.
Hence, in this case, it is concluded that the correct answer is option A, D, and C accordingly.

Im not in AP sorry.......
Answer:
Explanation:
Given that:
the quantity of solar radiation = 7,000,000cal/m²/day
The producers' gross productivity in the salt marsh (mostly microscopic algae) is 0.0040 g/cm²/day.
= 0.004 × 2920 cal × 10000 m²/ day
= 116800 cal/m²/day
The respiration requirement is 35% of the gross primary productivity.
i.e 35% of 116800 calories/m²/day
= calories/m²/day
= 40880 calories/m²/day
The Net primary productivity NPP = Gross productivity - Respiration requirement
=( 116800 - 40880)
calories/m²/day
= 75920 calories/m²/day
We can calculate the efficiency of photosynthesis by using the formula:
