Transcript of The Carbon Cycle

Exhaling Carbon Dioxide
Consumption of plants which reduce atmospheric CO2

The Carbon Cycle
Decayed Organisms
Consumers & Respiration

The animals eat the plants so they get the carbon and when they respire, they expel or release the carbon dioxide from their bodies.
The sun will give sunlight to the plants and other producers.

It will help them in engaging into photosynthesis.

In Photosynthesis, it pulls out the carbon in the air and makes it sugar which feeds animals and plants.

CO2 + H20 + 's Energy = glucose + oxygen

Plants have carbon and other organic compounds.

The animals eat those plants therefore they will get the carbon.

When they die and decay, the carbon shall be released to the environment.

Respiration of Plants
Plants respire, too. Usually, they respire at nighttime taking in oxygen and releasing carbon dioxide.

They also respire at day also known as PHOTO RESPIRATION.

They are 2 Main types of Plant respiration.

Photorespiration occurs when the CO2 levels inside a leaf become low.
Photosynthesis - converts sunlight into energy.

Respiration- act of breathing in & out

Transpiration - exhaling water vapor through skin.

Stomata - small epidermal pore; passageway of water vapor

phosphoglycolate - enzyme that catalyzes chemical reaction
Aerobic - oxygen-based
2 types of plant respiration
Anaerobic - occurs without oxygen.
It breaks down glucose into pyruvic acid then this acid undergoes fermentation which cells use for energy proudction.

pyruvic acid - colorless acid
fermentation - breaking down a substance into simpler substances
In organic compounds in plants and animals, there may be decomposers like fungi and bacteria.

They also undergo cellular respiration.
Decomposers are organisms that break down dead or decaying organisms.
When wood and coal are burned as fuel, carbon dioxide is released in the air.
Carbon Dioxide
Coal is a fossil fuel that is formed when wood or other plant parts are buried in great depths for milleniums.
Carbon Dioxide is released in to the air.
Industry which includes vehicles, factories, and electricity power plants can help in releasing carbon in the environment, too.
The bottom of the ocean is rich in carbon:
Carbonate Ions
Bicarbonate Ions
The diffusion of CO2 in water produces these ions.
When these ions are combined with:
Calcium = Calcium Carbonate
Magnesium = Diatoms
When diatoms or other oragnisms die, their remains settle at the bottom and slowly dissolve.
They become carbon compounds and brought up by upwelling.
Algae & Phytoplankton :

contain chlorophyll
absorbs carbon dioxide
can photosynthesize

Too much Carbon Dioxide in the world is bad for us.

So we need to help reduce carbon by not using CFC products or avoid smoke belching.

Have a good day. :>
Volcanic Eruptions release Carbon Dioxide, too.
