Plants grow through the cracks and animals dig in the soil, further breaking apart and dislodging structures. Chemical processes, like the oxidation of iron, cause unsightly rust. Carbonic acid, a result of carbon dioxide mixing with water, dissolves limestone. Acid rain also wears down stone.
Hypoxia is inadequate oxygen delivery to body tissues. The form of hypoxia that reflects poor oxygen delivery resulting from too few Rbcs of from Rbcs that contain abnormal or too little hemoglobin is the Anemic hypoxia. Hemoglobin plays a substantial role in carrying oxygen through out the body, and when it is deficient, anemia can result, causing anaemic hypoxia' if tissue perfusion is decreased. Iron deficiency is the most common cause of anemia.
Well there are a few different features such as the silver-grey metallic appearance, capable malleability, effective conductivity and lustrous shine !
I think that it's Photosynthesis?
