When corals eject their intracellular symbiotic organisms, their color is lost along with the zooxanthellae's photosynthetic ability. This leads to the death of the coral. Algal blooms simply involve the rapid growth of algae over a short period of time. Upwelling involves the process by which deep, nutrient-rich water rises up and gets mixed with the water higher in the ground.

The greenhouse effect plays a role in all of the options because of the interaction between the layer of gasses surrounding the earth and the solar radiation that approaches the earth. An easy way to remember this is to follow the path of solar radiation traveling from the sun to the earth and think of all the possible ways in which this radiation can travel. The radiation can bounce off and not enter, it can enter and be absorbed in the surface, or it can enter and both bounce off the earth's surface and then be absorbed.

Water vapor is the most abundant greenhouse gas in the Earth's atmosphere. Infrared radiation that gets absorbed and reflected by the Earth's surface gets trapped and reflected back to the Earth's surface by greenhouse gasses in the atmosphere in a process known as the "greenhouse effect."

levels can be accounted for by a combination of both the 
tilt of the Earth on its axis by as well as the revolution of the Earth around the sun. These two factors in conjunction with one another create the seasons. Since the Northern Hemisphere has vastly more plant coverage compared to the Southern Hemisphere, the Earth can uptake more carbon dioxide during the summer and spring seasons due to high levels of photosynthesis; however, when the Northern Hemisphere is in fall and winter, many of its plants cannot photosynthesize, leading to a spike in atmospheric carbon dioxide.

The Northern hemisphere has a much larger basal area comparatively to that of the Southern hemisphere. When the Northern hemisphere is in winter, many of its plants are not able to photosynthesize, therefore the global 
levels rise due to much fewer plants actively uptaking that 
for their photosynthetic processes. By the same token, when the Northern hemisphere is experiencing spring and summer, the carbon dioxide levels fall due to higher photosynthetic activity.

Methane gas produced by livestock is a very potent greenhouse gas, with molecules that trap far more heat in our atmosphere than carbon dioxide. When methane is burned, carbon dioxide and water vapor are released into the atmosphere, but these vapors have a relatively benign impact on global warming when compared to the release of methane, had it not been used as fuel. Therefore, harvesting methane gas from agricultural waste and livestock prevents potent greenhouse gases from escaping into the atmosphere and also reduces dependence on energy derived from fossil fuels.

The greenhouse effect occurs as the temperature within the Earth's atmosphere rises. Greenhouse gases trap the heat within the Earth's atmosphere. As sunlight enters the Earth's atmosphere, it passes through the gaseous layer and the Earth's surface absorbs part of the energy and reflects some energy. These reflected rays of energy get trapped between the Earth's surface and the atmosphere. Some common greenhouse gasses include: carbon dioxide, methane, nitrous oxide, and tropospheric ozone. Helium and nitrogen are two gases in the atmosphere, but they do not contribute to the greenhouse effect.
