The Carbon Cycle
Transcript of The Carbon Cycle
Cellular Respiration- the process through which cells break up sugars into a form that the cell can use as energy (ATP)
Combustion- the process of burning something
Photosynthesis- the process through which plants use sunlight, water, & carbon dioxide to create glucose for food
Decomposition- the process of organic material breaking down into smaller molecules that can be used by other organisms in an ecosystem
The Carbon Cycle
Photosynthesis and cellular respiration are what form the term "carbon cycle".
In photosynthesis, plants use carbon dioxide with water and solar energy to make carbohydrates.
Autotrophs and heterotrophs use oxygen to break down carbohydrates during cellular respiration, and the byproducts of cellular respiration are carbon dioxide and water.
Decomposers release carbon dioxide into the atmosphere when breaking down organic compounds.

Human Influences on the Carbon Cycle:
The atmospheric carbon dioxide has risen more than 30% in the last 150 years because of humans burning fossil fuels and other organic matter
The remains of organisms are transformed into energy-rich molecules by decay, heat, and pressure
When fossil fuels are burned the molecules and carbon dioxide are released.
Vegetation can help absorb carbon dioxide from the atmosphere, but when forests are cut down to make land there is less of it

Carbon Cycle- the process in which carbon travels from the atmosphere into organisms and the earth, and then back into the atmosphere.
CO2 Used by Plants for Photosynthesis - The primary producers , also known as photoautotrophs, are constantly removing carbon dioxide from the atmosphere through the process of photosynthesis (the process in which green plants make food for themselves in presence of sunlight.)
Consumption by Animals - The carbon present in the food made by green plants reaches animals through the food chain. Carnivorous animals receive this carbon when they eat other animals.
First, carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning).
Next,carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis . These producers then put off oxygen.
Then,animals feed on the plants, passing the carbon compounds along the food chain. Most of the carbon these animals consume however is exhaled as carbon dioxide. This is through the process of respiration. The animals and plants then eventually die.
Finally,the dead organisms are eaten by decomposers. The carbon that was in their bodies is then returned to the atmosphere as carbon dioxide. In some circumstances the process of decomposition is prevented. The decomposed plants and animals may then be available as fossil fuel in the future for combustion.
Ocean Intake - Carbon dioxide is continuously being dissolved in the seas and oceans through the process of diffusion.
Decay and Decompose - When living organisms die, their bodies decay and decompose. This happens due to various natural reasons. The energy as well as the carbon dioxide present in their bodies is released by the chemical reactions taking place on the body.
Formation of Fossil Fuels - As plants and animals die and get buried under the ground after millions of years, they change into fossil fuels due to high pressure and other physical and chemical changes.
Use of Fuels for Industrial Purposes - Fossil fuels stored in the heart of the Earth are dug out and used by industries for purposes of energy production. It is also used as a raw material for other purposes.
Carbon Emissions - The fuel used by the companies leads to the production of waste gases. These gases also contain a large amount of carbon dioxide.
Respiration by Plants and Animals - Carbon dioxide is regularly being returned to the atmosphere by the process of respiration in plants and animals. Burning of wood and fossil fuels in industries and automobiles also releases carbon dioxide.
