Question

If a terrestrial ecosystem has a net primary production of 3,000 kcal/m²/yr and a cellular respiration rate of 2,000 kcal/m²/yr, what is the gross primary production for this ecosystem?

a) 100 kcal/m²/yr

b) 500 kcal/m²/yr

c) 1,000 kcal/m²/yr

d) 5,000 kcal/m²/yr

Answer 1

The gross primary production for this terrestrial ecosystem is 5,000 kcal/m²/yr.

Step-by-step explanation:

The gross primary production for this terrestrial ecosystem can be calculated by adding the net primary production and the cellular respiration rate together. In this case, the net primary production is 3,000 kcal/m²/yr and the cellular respiration rate is 2,000 kcal/m²/yr. So, the gross primary production would be 3,000 kcal/m²/yr + 2,000 kcal/m²/yr = 5,000 kcal/m²/yr.
