Has the chemical composition of ocean water remained constant through geologic time? No, at the early stages it was very high carbon dioxide and sulfur dioxide, the gases like chlorine became dissolved in the atmosphere and then fell as acid rain. The input and output balance between these chemicals and the ocean similar in composition to ours today. (Ch.1 Pg. 24) 2. Could the earth’s mantle have produced enough water to fill the oceans? Yes, because gases from within earth rose to the surface where they were expelled to from earth's atmosphere. 3. What do we call organisms that can make their own food from inorganic carbon sources? Early Autotrophs derived energy from inorganic compounds at deep-water hydrothermal vents using a process called chemosynthesis. (Ch.1 pg. 27) 4. What do we call organisms that can break down organic molecules produced by other organisms to release energy? Heterotrophs- animals and bacteria that depend on the organic compounds produced by other organisms as food. Organisms not capable of producing their own food by photosynthesis. (Ch.1 pg. 27) 5. Why did the separation of the Earth into layers occur? As a result of density stratification, high-density materials moved near core, low-
