Impact Of The Carbon Cycle

Question 1

What are the impacts of carbon cycle on land

Answer 1

Carbon= plant growth via photosynthesis, decomposition wouldn’t take place - nutrients would never be recycled

Question 2

Impacts on land of increasing carbon in atmosphere

Answer 2

More CO2 available to plants= more photosynthesis
Increased growing season due to warmer temps
Melting of permafrosts due to increased temps
Increase wildfires= more atmospheric CO2

Question 3

Impact of carbon cycle in oceans

Answer 3

CO2 is dissolved into the oceans from the atmosphere.
Organisms use this CO2 during photosynthesis to form calcium carbonate shells and skeletons. Carbon is then passed along the marine food chain

Question 4

Impacts in oceans of increasing atmospheric carbon

Answer 4

More acidic oceans, 30% change in ocean acidity since 1750
Warmer ocean temps= decline in phytoplankton= more CO2 in atmosphere
Sea ice melting= loss of habitat for species of algae and loss of hunting grounds for larger predators
Less CO2 dissolved in sea
Sea level rise- oceans predicted to rise between 0.8 and 2m by 2100

Question 5

Impacts of the carbon cycle in atmosphere

Answer 5

Affects amount of gases containing carbon in the atmosphere, ensuring the climate is warm enough to support life on Earth
concentrations increase= temps increase

Question 6

Impacts of carbon cycle on global climate

Answer 6

High photosynthesis and respiration= high levels of humidity, amount of cloud cover and affects rainfall
Deforestation= drier and less humid areas
