Answer:
a) near the North Pole
Explanation:
As our Earth has a little bit inclination, the heat from the sun it does not reach the same to all the planet´s surface. That is one reason, why we have the imaginary lines that are called, latitudes, there are lines that start from the equator until the north pole, and in the center or our planet at 0 °, is the hottest temperatures, but as moving to the north, the degrees of the latitude, start to increase, in this way, the temperature will decrease. This relation ship is inverse proportional, as we increase the latitude, the temperature will decrease. In the examples that we have, the North Pole has 90° so is the highest latitude, so it will present the lowest temperature.

Answer:
Primary productivity = 1000 gm/year/sq. meter
Explanation:
Primary productivity is defined as the difference betweeen main gross manufacturing and breathing energy. For the herbivorous, this is the energy available.
It is expressed as "gm/year/sq. meter" = gm/yr/m^2
or "kcal/year/sq. meter" = k cal/year/m^2
In the present case,
Gross primary production = 2000 gm/yr/m^2
Used for respiration purpose = 1000 gm/yr/m^2
So, Primary productivity = (2000 - 1000) gm/year/sq. meter
Primary productivity = 1000 gm/year/sq. meter
