b.
There is frequent flooding and the soil is nutrient-poor.
c.
There is frequent flooding and the soil is nutrient-rich.
d.
The soil is frozen and contains pockets rich in nutrients.

Answer 1

a. The soil is frozen and generally low in available nutrients. Permafrost and a very short, cold growing season prevent deep roots and slow decomposition, so plant growth is limited.
