Question

7.3) how does the burning of fossil fuel affect the carbon cycle?
7.4) where does the oil in your car come from?
7.5) how can too much carbon dioxide lead to global warming?
7.6) why does the carbon cycle closely follow the energy transformations learned in lesson 5?
7.7) what molecule do plants and plankton make during photosynthesis?
7.8) when you burn anything, ____________ is released into the atmosphere.
7.9) do you think carbon emissions by humans should be regulated? give your answer and write at least five sentences backing your answer.

Explanation:

7.3) Burning fossil fuels releases stored - carbon into the atmosphere as carbon dioxide, increasing its concentration and disrupting the natural carbon cycle.
7.4) The oil in a car comes from ancient organic matter (plants and animals) that was buried and subjected to heat and pressure over millions of years, forming petroleum in underground reservoirs.
7.5) Carbon dioxide is a greenhouse gas. It absorbs and emits infrared radiation, trapping heat in the Earth's atmosphere and leading to global warming.
7.6) The carbon cycle is linked to energy transformations as carbon - containing compounds store energy. Processes like photosynthesis and respiration involve energy transfer and carbon movement.
7.7) Plants and plankton make glucose ($C_6H_{12}O_6$) during photosynthesis, using carbon dioxide and water with the help of sunlight.
7.8) When you burn anything, carbon dioxide (and sometimes other gases like water vapor) is released into the atmosphere.
7.9) Yes, carbon emissions by humans should be regulated. Firstly, high carbon emissions cause global warming, leading to rising sea - levels and threatening coastal communities. Secondly, it results in more extreme weather events such as heatwaves and heavy rainfall. Thirdly, it affects ecosystems, endangering many species. Fourthly, it can lead to ocean acidification, harming marine life. Finally, regulating emissions can encourage the development of clean and sustainable energy sources.

Answer:

7.3) Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, increasing the atmospheric carbon pool and disrupting the natural balance of the carbon cycle.
7.4) It comes from the remains of ancient plants and animals that were transformed into petroleum through geological processes over millions of years.
7.5) Carbon dioxide is a greenhouse gas. It traps heat in the Earth's atmosphere, causing the planet's average temperature to rise.
7.6) Energy transformations often involve carbon - based compounds. For example, in photosynthesis, solar energy is used to convert carbon dioxide into glucose, and in respiration, energy is released as carbon is cycled back to carbon dioxide.
7.7) Glucose ($C_6H_{12}O_6$).
7.8) Carbon dioxide.
7.9) Yes. Carbon emissions cause global warming, which leads to sea - level rise, extreme weather, ecosystem damage, ocean acidification, and regulating them can drive clean energy development.
