understanding carbon cycle

Question 1

carbon cycle and lithosphere connection

Answer 1

carbon is stored in fossil fuels and released through volcanic activity

Question 2

carbon cycle and hydrosphere connection

Answer 2

ocean absorbs carbon (carbon-sink)

Question 3

carbon cycle and biosphere connection

Answer 3

Plants absorb carbon dioxide from photosynthesis and release it back from respiration and decomposition.

Question 4

carbon cycle and atmosphere

Answer 4

contains carbon dioxide- then exchanged to hydrosphere, lithosphere and biosphere.

Question 5

natural energy transfer within carbon cycle

Answer 5

photosynthesis, respiration, decomposition

Question 6

human energy transfer within carbon cycle

Answer 6

burning fossil fuel, deforestation, agricultural practices

Question 7

burning fossil fuels impact on carbon cycle

Answer 7

humans burning fossil fuels is releasing large amounts of CO2 in the atmosphere, enhancing greenhouse gases leading to global warming

Question 8

deforestation impact on carbon cycle

Answer 8

reduces number of trees available to absorb the CO2 in photosynthesis, meaning that CO2 goes straight to atmosphere

Question 9

consequences of global warming

Answer 9

meting ice and glaciers, extreme weather conditions, sea level rise

Question 10

matter moving through photosynthesis in carbon cycle

Answer 10

plants, algae and some bacteria use sunlight to convert carbon dioxide from the atmosphere and water into glucose and oxygen.

Question 11

matter moving through respiration in carbon cycle

Answer 11

plants and animals break down glucose during cellar respiration to release energy, emitting carbon dioxide

Question 12

matter moving through decomposition in carbon cycle

Answer 12

converts organic carbon into CO2 and methane, which is released into the atmosphere or soil which returns carbon to environment

Question 13

matter moving through anthropogenic emissions in carbon cycle

Answer 13

increase the carbon levels, enhancing greenhouse gas effect

Question 14

matter moving through volcano in carbon cycle

Answer 14

natural process that adds CO2 into atmosphere from lithosphere

Question 15

matter moving through defecation in carbon cycle

Answer 15

breaks down the waste products, releasing carbon back into the atmosphere
