Practice Problems:
1. 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 _____m3. 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
2. The gross primary productivity of a meadow in south
eastern Kansas is found to be 38,000 kcal/m2. Respiration
which is measured by the amount of CO2 released is 13,500
kcal/m2, what is the net primary productivity for this
ecosystem, in kcal/m2 per year?
