reforestation - pack 16

Question 1

describe a young forest with respect to how it takes in and releases co2

Answer 1

turning co2 into wood

Question 2

what is the relationship between respiration and photosynthesis

Answer 2

respiration will be less than photosynthesis

Question 3

a young forest system is

Answer 3

a net absorber of co2

Question 4

what happens as the trees (plantation) gets older

Answer 4

the system will move towards a balance between photosynthesis and respiration and the forest will be no longer a net absorber and a carbon store with carbon locked up in the biomass

Question 5

how would the earths forests be used as a carbon store

Answer 5

could soak up extra co2 as increases co2 concentrations and higher temp stimulate photosynthesis leading to extra growth

Question 6

what is the problem with using the earths forests being used as a carbon store

Answer 6

there will be a limit to how much or for how long the worlds forests can soak up extra co2

Question 7

describe what actions can be taken to slow down further increases in atmospheric co2 concentrations

Answer 7

planting trees, less use of fossil fuels, inspiring energy efficiency, capturing co2 and putting it in the ocean - microscopic algae act as carbon sinks

Question 8

what are other problems that we are facing when trying to find green alternative energies

Answer 8

manufacture and instillation of renewable energy sources (wind farms) will affect emissions (people consider them unsightly and a danger to flying birds)
