HELP, 100 POINTS! Identify one source of carbon that can be found in each of these four spheres: atmosphere (air), geosphere (land), biosphere (living organisms) and hydrosphere (water).

The mitochondria has been described as the engine of the cell. Why is this a fitting nickname? How is this organelle involved in the process of cellular respiration?

Describe the process of photosynthesis in plants. Why is this process important to animals and humans?

How are the processes of cellular respiration, photosynthesis and carbon cycle related to each other?

Explain how one of the processes discussed in this module (photosynthesis, cellular respiration or the carbon cycle) apply to both the Law of Conservation of Matter and Law of Conservation of Energy.

1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.

2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!

3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.
