Answer:
The movement of carbon from the atmosphere to the lithosphere (rocks) begins with rain. Atmospheric carbon combines with water to form a weak acid—carbonic acid—that falls to the surface in rain. The acid dissolves rocks—a process called chemical weathering—and releases calcium, magnesium, potassium, or sodium ions.

Answer:
<em>Clostridium perfringens</em>
Explanation:
<em>Clostridium perfringens</em> is a bacterium characterized by being a large, gram-positive, boxcar-shaped bacillus.
It is part of the facultative aerobic bacteria group (they can survive both in the presence or absence of oxygen) and is also a spore-forming bacterium (spores are small structures capable of generating new bacteria).
<em>Clostridium perfringens</em> can cause food poisoning, which results from the ingestion of contaminated food (usually meat and animal products) by the bacteria.
Once in the small intestine, the bacteria releases the toxin that usually causes diarrhea.
