4.3 Carbon Cycling

Question 1

List the forms of Carbon Dioxide

Answer 1

Atmospheric Gases, Oceanic Gases, As Organic Material, As Non-Living Remains

Question 2

Examples of CO2 as Atmosphere gas

Answer 2

Carbon Dioxide (CO2), and Methane (CH4)

Question 3

How are atmospheric gases transformed and transferred

Answer 3

Transformed into the atmosphere as a waste product of aerobic respiration

Transferred to organic material via photosynthesis and into the ocean via molecular diffusion

Question 4

Examples of Oceanic Gases

Answer 4

Dissolved bicarbonates and calcium carbonates

Question 5

What is feeding

Answer 5

How chemical energy in carbon compounds flows through food chains by means of feeding

Question 6

How do consumers obtain energy

Answer 6

Through the carbon compounds in the organisms on which they feed

Question 7

Define Egestion

Answer 7

The removal of feces from an animal that contains carbon

Question 8

How are fuels generally formed

Answer 8

Dead organisms are unable to fully decompose in acidic and anaerobic conditions. They become sediment that may become fossil fuels, coal, oil or natural gas

Question 9

How is peat formed

Answer 9

When partially decomposed organic matter is compressed in anaerobic/acidic conditions such as waterlogged soil. It forms a brown soil like carbon rich matter
