Answer:
D.
Explanation:
Basically survival of the fittest. (if possible, please mark me brainliest ily <3)
<span>If the grasses on a 100-hectare area of grassland grow at an average rate of 1 cm/day, the average volume of grass that is added to the grassland each day is 10,000 m3
</span><span>If the density of the grasses that grow in the grassland average 400 kg/m3, the NPP is approximately 4000 g/m2/day or 1460000 g/m2/year
Equations:

<span>
100 hectare (x) 10,000 m2/hectare = 1(x)106 m2 (x) 0.01 m/day =</span></span>
<span>
<span>
10,000 m3/day (x) 400 kg/m3 (x) 1000 g/1 kg = 4 (x) 109 g/day / 1 (x) 106 m2 =</span></span>
<span>
<span>
4000 g/m2<span>/day (x) 365 day/year = </span>
