Answer:
Option E, Both increased acidity of deep waters and changes in the growth of bottom-dwelling organisms with calcium-carbonate shells
Explanation:
When high concentration of CO2 is pumped into the ocean at its greater depths, CO2 is absorbed extensively by the ocean which changes the pH of ocean water and makes it more acidic. The high acidity of ocean water is due to the release of free hydrogen ions. Excess of hydrogen ions make the carbonate ions less abundant due to which the organism that make carbonate shell will suffer as they may not get sufficient carbonate ions to calcify their outer coverings.
Hence, option E is correct
Answer:
Nonvascular plants include liverworts, hornworts and mosses.
Answer:
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. ... Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms
