All Flashcards
What are the environmental consequences of burning fossil fuels?
Increased atmospheric CO2, global warming, climate change.
What are the environmental consequences of deforestation?
Reduced CO2 absorption, increased atmospheric CO2, habitat loss.
How does increased atmospheric CO2 affect global climate?
Leads to the greenhouse effect, causing global warming.
What is the effect of agricultural practices on carbon emissions?
Can contribute to carbon emissions and soil degradation.
What are the steps of photosynthesis?
- Plants absorb CO2 from the atmosphere. 2. Plants use sunlight to convert CO2 and water into glucose and oxygen. 3. Oxygen is released into the atmosphere.
What are the steps of cellular respiration?
- Plants/animals take in glucose and oxygen. 2. Glucose is broken down to produce energy (ATP). 3. CO2 and water are released as byproducts.
Describe the process of carbon exchange in the ocean.
- The ocean absorbs CO2 from the atmosphere. 2. CO2 dissolves in seawater. 3. Some CO2 is released back into the atmosphere, while some is used by marine organisms.
Describe the process of decomposition.
- Dead organisms or organic matter are present. 2. Decomposers (bacteria, fungi) break down the organic material. 3. Carbon is released back into the soil and atmosphere as CO2.
Outline the process of sedimentation in the ocean.
- CO2 dissolves in ocean water. 2. CO2 combines with calcium ions. 3. Calcium carbonate forms and sinks to the ocean floor, storing carbon in sediments.
Describe the process of fossil fuel formation.
- Ancient organisms die and are buried. 2. Over millions of years, heat and pressure transform the organic matter. 3. Fossil fuels (coal, oil, natural gas) are formed, storing carbon.
What are the steps of photosynthesis?
CO2 absorption, conversion to glucose and oxygen, carbon storage.
What are the steps of cellular respiration?
Glucose breakdown, energy (ATP) production, CO2 release.
What are the steps of decomposition?
Breakdown of organic matter, release of carbon into soil/atmosphere.
Describe the process of carbon exchange in oceans.
Ocean absorbs CO2 from atmosphere, some CO2 is released back.
Outline the process of sedimentation in the carbon cycle.
CO2 combines with calcium ions, forms calcium carbonate, sinks to ocean floor.
