carbon cycle

Question 1

what organic and inorganic molecule is carbon found in

Answer 1

organic- glucose, proteins, lipids

inorganic- co2

Question 2

draw the carbon cycle and explain each process

Answer 2

Photosynthesis - Producers, like plants, absorb CO2 from the atmosphere and convert it into organic molecules.

Consumption - Carbon is passed through food chains as organisms consume other organisms.

Respiration - Organisms use oxygen and carbohydrates to release energy, releasing CO2 back into the atmosphere.

Decomposition - Dead organic matter is broken down by microorganisms, which releases CO2 into the environment.

Formation of fossil fuels - Carbon, stored in dead organic matter that does not decompose due to high temperature and pressure, is transformed over millions of years into fossil fuels, including coal and oil.

Combustion - The burning of fossil fuels reacts stored carbon with oxygen, releasing CO2 into the atmosphere.

Weathering - Carbon stored in sedimentary rocks is released back into the environment through weathering processes.

Volcanic activity - Tectonic plate movements can lead to the release of CO2 from volcanic eruptions.

Question 3

why should the amount of carbon in atmosphere stay the same

Answer 3

photosynthesis and respiration should level the inputs and outputs out

Question 4

what is a carbon sink?

give biotic and abiotic examples

Answer 4

-reservoirs/ stores of carbon

abiotic- limestone, fossil fuels

biotic- humus, plants
