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 . if the density of the grasses that grow in the grassland average 400 kg/m3, the npp is approximately g/m2/day or g/m2/year

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

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

  the tendency to view one's own culture  and  group as superior  is called. cultural relativism.

The earth's inner core is the earth's innermost part. it is primarily a solid ball with a radius of about 1,220 km (760 miles), which is about 70% of the moon's radius.[1][2] it is composed of an iron–nickel alloy and some light elements. the temperature at the inner core's surface is approximately 5,700 k (5,430 °c), which is about the temperature at the surface of the sun.
