Answer:
*How are plants and trees in the forest important in the carbon cycle?
-Forests sequester or store carbon mainly in trees and soil. While they mainly pull carbon out of the atmosphere—making them a sink—they also release carbon dioxide. This occurs naturally, such as when a tree dies and is decomposed (thereby releasing carbon dioxide, methane, and other gases).
*In what ways does carbon enter the biotic part of the ecosystem?
-Carbon as carbon dioxide, an abiotic factor, enters the biotic realm of an ecosystem through photosynthesis by either plants or photosynthetic microorganisms.
