Carbon as a cycle
Carbon needs to be cycled through the different components of our environment. It needs to be cycled through the living components as well as the non-living components.
another term for living is "biotic components"
another term for non-living is "abiotic components"
Why is the Carbon cycle a BIOGEOCHEMICAL cycle?
The moving of carbon around the different components involves biological interactions, geological activities and chemical reactions.
Why is carbon important to all things?
We need it for our own cells because living things are made out of carbon. It's the key element in vital nutrients like- fats, carbohydrates, proteins and nucleic acids.
What are the living things on Earth called?
Carbon-based life forms.
something that acts like a storage source. Storage source for carbon.
As CO2 in the atmosphere (0.03% air)
Carbonate (CO32-) Bicarbonate (HCO3-)
As carbonate and bicarbonate dissolved in the oceans. (oceans- bicarbonate formula) (baking soda- carbonate formula)
As calcium carbonate (CaCO3) in rocks (limestone) and shells.
Carbon in molecules of once living things
As carbon in the molecules of once living things- detritus, oil, gas, coal, fossil fuels
Carbon in molecules of living things
As carbon in the molecules of living things like producers, consumers and decomposers - fungus, bacteria. Herbivore, Carnivore, Omnivore
Greenhouse gas which acts to increase the temperature of our planet, which is called a greenhouse effect.
The radiation is absorbed by the atmosphere and the Earth, which re-emits the radiation as heat.
How does the carbon dioxide increase the greenhouse effect?
Too many greenhouse gases (like carbon) cause a run-away greenhouse effect, which leads to global climate change.
CH3- Methane N2O- Nitrous oxide H2O -vapor
Producers, consumers and decomposers
Through the process of living and dying producers, consumers, and decomposers help cycle carbon through the biotic and abiotic components of the environment.
The waste and remains of once living organisms.
Fossil fuels come from the dead remains of ancient plants and animals. 90% of the world's energy comes from fossil fuels
Short-term carbon reservoirs
producer, consumers, detritus, decomposers.
long-term carbon reservoirs
death and decomposition
dead, plant and animals
two components of detritus:
dead and plants/ animals
two different paths that detritus can take:
decompose the detritus into nutrients which can be assimilated by plants. OR undergoes another process that produces fossil fuels
is a consumers and producers breathe out carbon dioxide.
What types of organisms perform cellular respiration?
plants and animals.
chemical equation for cellular respiration
glucose + oxygen = carbon dioxide + water + energy.
what is energy used for in cellular respiration?
power the plant or animals.
what happens to carbon dioxide in cellular respiration?
because it's toxic it's released into the atmosphere where it can be used by plants during photosynthesis.
what happens to the water in cellular respiration?
water is a harmless product which adds to the plants or animals own water content.
A chemical process performed by plants. In this process they take carbon dioxide from the air, water from the soil, and use the energy from sunlight to produce glucose and oxygen.
What types of organisms perform photosynthesis?
plants or producers.
Chlorophyll in photosynthesis
A green pigment called chlorophyll helps capture the sunlight needed for the reaction.
chemical equation for photosynthesis:
carbon dioxide + water + sunlight (chlorophyll) = glucose + oxygen
the transfer of carbon through the organisms in a food web.
involves ancient plants which have been buried for hundreds of millions of years to produce fossil fuels.
how is peat and coal formed?
the decomposition was slow due to the swamp's anaerobic (low oxygen) conditions which created peat. If the peat was covered in sediment and subjected to intense heat and pressure it forms coal.
the cutting down of forests.
deforestation indirectly lead to an increase on carbon dioxide in the atmosphere
less trees to perform photosynthesis which removes carbon dioxide from the atmosphere.
three processes that increase in atmospheric carbon dioxide:
cellular respiration, combustion and deforestation.
involves the burning of a fuel source that contains hydrocarbons.
majority of the human generated combustion come from?
The burning of trees and fossil fuels. It releases carbon dioxide into the atmosphere which contributes to the greenhouse effect.
the disadvantages of combustion that effects our planet:
car exhaust, running appliances, coal fired plant.
