Carbon Cycle

Question 1

The air around us contains a small amount of

Answer 1

CO2 (carbon dioxide)

Question 2

this CO2 is used by what during when

Answer 2

plants in photosynthesis

Question 3

Photosynthesis is the only process that

Answer 3

takes CO2 out of the cell (cell respiration)

Question 4

What is this CO2 during photosynthesis built into

Answer 4

sugars and other complex carbon compounds

Question 5

After it is built into sugars and complex carbon compounds, what happens

Answer 5

it is converted into C6H12O6 (glucose)

Question 6

Equation for photosynthesis

Answer 6

carbon dioxide+ water (CO2+H2O)
TO GIVE
sugar+ oxygen (C6H12O6+O2)

Question 7

Plants are eaten by

Answer 7

(your… im not gonna say it)

animals

(mom)

Question 8

or animals feed on

Answer 8

other animals

Question 9

this eating of organisms process is called

Answer 9

feeding

Question 10

what happens to the sugar during feeding

Answer 10

it gets into the cells in the animal’s body

Question 11

(sugar into animals’ bodies) this means that

Answer 11

glucose in plants goes to glucose in animals or animal to animal

Question 12

In cells, the sugar is

Answer 12

broken down into CO2 and water to produce energy

Question 13

this CO2 and water forming energy process is called

Answer 13

respiration

Question 14

Therefore, this respiration means that

Answer 14

CO2 is put back into the atmosphere

Question 15

after this respiration, what is converted into what

Answer 15

C6H12O6 is converted into CO2

Question 16

Respiration Equation

Answer 16

C6H12O6+O2
INTO
Co2+H2O+ energy (ATP)

Question 17

what is ATP

Answer 17

a molecule that keeps the energy inside of it so it wouldn’t exist as heat energy

Question 18

What happens to animals and plants when they die

Answer 18

they decay

Question 19

In this decaying process, what happens

Answer 19

bacteria and the other decomposers feed on them. They too respire and release CO2 back into the atmosphere

Question 20

therefore this decaying is another example of the process of

Answer 20

respiration

Question 21

When decomposers decay the animals, what else happens

Answer 21

the carbohydrates are converted into carbon back into the soil
carbohydrates—>carbon—>soil

Question 22

this conversion to carbon formula

Answer 22

C6H12O6 into C (glucose to inorganic carbon)

Question 23

What happens if there is not enough O2

Answer 23

for complete decay, the dead remains pile up and are softened into soft, black peat (eg in bogs and swamps)

Question 24

What is this lack of oxygen decay done by

Answer 24

bacteria respiring anaerobically

Question 25

What happens to the peat overtime

Answer 25

it gets buried and hardens into coal (glucose to fossil fuels)

Question 26

what are formed in a similar way (to the coal) and from what

Answer 26

The other fossil fuels (oil and natural gas) are formed in a similar way from tiny marine organisms sunk to the bottom of the sea

Question 27

What happens when coal is burned in factories

Answer 27

CO2 is released back into the atmosphere. By man burning coal, the carbon in coal is returned to the atmosphere

Question 28

Coal is converted to

Answer 28

CO2

Question 29

this last process is

Answer 29

combustion

Question 30

i genuinely have no more time

Answer 30

check the diagrams and the notes are basically the same, watch the vid
