Answer:
B. Aerobic bottom water
D. High organic productivity in the overlying oxygen rich water
Explanation:
A Shale is a sedimentary rock usually formed from silt and clay-size mineral. There are different colors of Shale. The Black Shale is formed under anaerobic conditions. This means that oxygen is deficient in the water where the Shale forms.
A little amount of organic materials is required for the formation of Black Shale and because Black Shale is formed in an environment lacking oxygen, an oxygen-rich water would not be necessary for its growth. Sediments are necessary in the formation of Black Shale.
Answer:
<em>it can, because...</em>
Explanation:
<em>Numerous studies have correlated drops in biodiversity—plus a diminished decent variety among warm-blooded creature species, specifically—to an expansion in the delivery of creature-invented infections to people. What's more, sound biological systems are vital for controlling the atmosphere and reducing air and water contamination.</em>
