If the carrying capacity for the North Atlantic cod on the Grand Banks of Newfoundland is 500,000 tons, when do you expect that
Murljashka [212]

Answer:

Option A

Explanation:

The carrying capacity of any given ecosystem is the maximum production that is achieved without environmental degradation. Now, since the production in option B and C is less than 500,000 tons (i.e carrying capacity of Grand Banks of Newfoundland), thus the rate of population growth would not be greatest and hence both option B and C are incorrect

Option D is also incorrect as production cannot be greater than carrying capacity or else environment will start degrading  

Hence, option A is correct
