Answer 1

Hint: The annual rainfall varies from place to place. In some places, the annual rainfall is more than average causing heavy vegetation, while in some places the average rainfall is less than average, causing a very little to no vegetation at all.

Complete Answer:
Now, let us analyze each option to find the correct answer.

Option A: Taiga is referred to the snow forest found in North America, the annual rainfall varies from 38 to 85 cm per year. Rainfall mostly takes place in summer. In tundra, the annual rainfall is very less as compared to Taiga which is around 18 to 25 cm. So, option A is incorrect.

Option B: The annual rainfall in Taiga is the same as that in grassland. They both lie in the range of 38 to 85 cm per year. So, option B is correct.

Option C: The annual rainfall in grassland varies between 38 to 85 cm per year while in tropical rain forest it is more than 200 cm per year, it's annual rainfall lies in between 200 to 250 cm per year. So, option C is incorrect.

Option D: In taiga, the annual rainfall varies between 38 to 85 cm per year while in temperate deciduous forest, it lies in between 100 to 150 cm per year. So, option D is incorrect.

Option E: In tundra, the annual rainfall lies in between 18 to 25 cm per year. In grasslands, the annual rainfall is between 38 to 85 cm per year. So, option E is incorrect.

So, the correct option is option B) Taiga and grassland.

Note: In case there is not enough rainfall, it can have the following affects,
Drought - There will be shortage of water for drinking, irrigating the crop, etc. As water levels are low, it can result in a rise of water temperature which can be lethal for aquatic organisms. Drying up of water bodies like rivers, lakes, oceans, etc.
