What led to the Quebec act, and what were the effects of its passage
maw [93]
The Quebec Act came about because British were worried that the French Canadians would support the American Revolution and since they had imposed some legislative acts on the Quebecois, which they did not like, they felt they should change these a little and gain support from the French-speaking population. The Quebecois were now able to use their own land systems, have a different government style to some extent, to be able to more freely practice Catholicism and gained more territory.

If you have a square meter of soil with one plant and the plant photosynthesizes 2000 g of carbon per year and respires 1000 gra
Hatshy [7]

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
