Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean.

Answer:
Annual mean temperature and annual mean precipitation.
Explanation:
The major biomes of North American biomes include almost every one of these biomes, Tundra., Boreal, Deciduous, Prairie, Desert, montane and tropical. All these biomes are effects or influence the distribution of organisms by several biotic and abiotic factors as the organism is found in the biomes that help in their livelihood.
Abiotic factors that influence the biomes that are present in North America most are temperature and precipitation that can be measured in Annual mean temperature and precipitation.
Thus, The correct answer is - annual mean temperature and annual mean precipitation.
