Question

in a section of forest, the gross primary productivity is 24 kg C / m^2 / year. Assume the net primary productivity is 40% of gross primary productivity. what is the net primary productivity of the area over two years?

Answer 1

Answer: The net primary productivity of the area over two years is 19.2 kg C / m^2.

Explanation: The net primary productivity is calculated as the gross primary productivity multiplied by the efficiency factor, which in this case is 40%.

So, net primary productivity = gross primary productivity × efficiency factor = 24 kg C / m^2 / year × 40% = 9.6 kg C / m^2 / year.

Over two years, the net primary productivity would be 9.6 kg C / m^2 / year × 2 years = 19.2 kg C / m^2.
