Deforestation is a source of anthropogenic, or human caused carbon dioxide emissions because cannot consume carbon dioxide molec
Roman55 [17]

Answer:

<h2>Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. </h2><h2 /><h2>The carbon cycle. </h2><h2>Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles. </h2><h2 /><h2>NOAA technicians service a buoy in the Pacific Ocean designed to provide real-time data for ocean, weather and climate prediction. </h2><h2>NOAA buoys measure carbon dioxide </h2><h2>NOAA observing buoys validate findings from NASA’s new satellite for measuring carbon dioxide </h2><h2>Listen to the podcast </h2><h2>Carbon storage and exchange </h2><h2>Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. </h2><h2 /><h2>The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. </h2><h2 /><h2>Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.</h2>

What changes in the food industry created the Western diet and can be linked to chronic diseases such as coronary heart disease,
Ronch [10]

Answer: by given steroid injection to animals

                                  <u>and </u>

                   increasing production of cheap calories of Sugar and Triglycerides  for use in food products

The attempt by farmers to maximize profit prompted them to give hormones e.g streroids to  animals to increase their  biochemical reactions therefore the the products yields e.g they  are  giving  steroids  to poultry  to  improve chicken, eggs production;and  to  cattle for improved beef and milk production.

In order to obtain maximum sugar and fats productions, cheap calories  forms of there  are being  produced. e,g fructose, maltose. if  maltose  is consumed in excess  it leads to  obesity, while fructose increases the level of cholesterol.These products  requires a lot of processing with different chemical products which leads to health problems after consumption

You track aquatic coastal levels of nitrogen and phosphorus at high latitudes and notice a sharp increase in the winter and then
nordsb [41]

Answer:

A considerable increase in phytoplankton populations in winter, and a greater increase in spring due to increase in light intensity.

Explanation:

Nitrogen and phosphorus are important nutrients required by phytoplankton populations. The growth of phytoplankton populations is dependent on the level of the availability of Nitrogen and Phosphorus in the presence of sunlight.

A rise in the aquatic coastal levels of nitrogen and phosphorus would result in a great increase in phytoplankton populations in spring, as stimulated by nutrient enrichment coupled with the availability of sunlight during spring. Phytoplankton populations would increase also in winter but not as high when compared to the rise in population in spring
