How is climate change affecting the tundra's ability to reduce carbon dioxide

In tundra, the winter is the dominating season.

Explanation:

In the changing season the soil starts to permafrost the organic matter in the soil remains stored inside the permafrost layer of ice. This prevents the dead and decaying matter which is high in concentration of carbon dioxide remain unexposed to the external environment. Thus the levels of carbon dioxide in the tundra environment remains in low concentration.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
