relative solar energy The graph indicates relative solar energy midday at two different locations on the planet throughout one year. Which statement accurately describes the differences in gross primary productivity between locations A and B?* A. B. month In December, GPP is greater for location B. In October, GPP is greater in location B than in Location A GPP is the same for locations A and B throughout the entire year. OIn March, GPP for location A is greater than the GPP for location B. In an aquatic ecosystem, 20.000 kcal /m²/ year was absorbed by producers through the process of photosynthesis. If the NPP was 8.000 kcal /m2/year, how much energy was lost to respiration? 28.000 kcal/m/vea

Suppose rice is planted on June 1.  If rice needs 1700 growing degree-days before it can be picked, and if the mean daily temperature for each day from June through August is 80oF, in about how many days will the rice be ready to be harvested? (Assume a base temperature of 60o F)   Question 27 options:   1)  20   2)  35   3)  40   4)  70   5)  85

An important result of extensive ant or termite activity in soils is: increased clay content of B horizons increased thickness of A horizons O increased available nitrogen O increased soil bulk density of both A andB horizons reduced phosphorus availability
