The cycling of carbon within ecosystems occurs through interactions among different organisms, and between organisms and the physical environment. In the atmosphere, carbon is found mostly in the form of carbon dioxide (CO2 ) gas. Carbon dioxide in the atmosphere can be taken in and used by some living things. What types of organisms can take in carbon dioxide gas?

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
