Four students were discussing how plants might react to the current change in climate. This is what they said:. Cassy: “I think plant species will adapt to climate changes and continue to exist as they do now.”

Four students were discussing how plants might react to the current change in climate. This is what they said: Cassy: “I think plant species will adapt to climate changes and continue to exist as they do now.” Will: “I think some plant species will adapt to climate changes but others will not adapt – these will not survive climate changes.” Jeremy: “I think plant species will acclimate to the climate changes and continue to exist as they do now.” Samantha: “I think plant species prefer the climate in which they grow best and will shift to be in the preferred climate if the climate changes.”

WHAT MAY HAPPEN TO MINNESOTA’S CLIMATE? HOW MAY CHANGES IN CLIMATE AFFECT MINNESOTA’S ECOSYSTEMS?
IT’S ALL ABOUT THE CLIMATE… CLIMATE is the prevailing weather conditions of a region averaged over long periods of time. Wikipedia
…AND THE BIOMES THAT RESULT NORTH AMERICA’S BIOMES A BIOME is a large land area characterized by a prevailing CLIMATE that supports a major ecological community type. Wikipedia
MINNESOTA’S BIOMES MN DNR Minnesota is unique in that it supports three major biomes, making it a grand ECOTONE… a transition zone between biomes.
