carbon cycle

Question 1

what is the carbon cycle

Answer 1

living tissue contains carbon, because they contain proteins, fats and carbohydrates. the carbon in these tissues is recycled in various processes

Question 2

what is the main reservoir for carbon

Answer 2

rocks

Question 3

step 1

Answer 3

carbon enters the atmosphere as. carbon dioxide from respiration and combustion

Question 4

step 2

Answer 4

carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis

Question 5

step 3

Answer 5

animals feed on the plant passing the carbon compounds along the food chain

Question 6

step 4

Answer 6

most of the carbon they consume is exhaled as carbon dioxide formed during respiration. these animals and plants eventually die

Question 7

step 5

Answer 7

the dead organisms are eaten by decomposers and the carbon in their body is returned to the atmosphere as carbon dioxide (in some conditions decomposition is blocked)

Question 8

step 6

Answer 8

the plant and animal material may then be available as fossil fuel for future combustion

Question 9

easy peasy version

Answer 9

1- carbon enters atmosphere as CO2 from rest and combustion

2- CO2 is absorbed by producers to make carbs in photosynthesis

3- animals eat plants passing the carbon compounds

4- the carbon is then exhaled as CO2. they then die

5- dead things are eaten my decomposers and the carbon is returned to the cycle as CO2

6- the plant/animal material can then be available as fossil fuels
