Launch Trying as hard as you can not to use your notes,

draw the oxygen cycle from yesterday.

What are some things in your daily life that carbon might be in?

What’s a carbon-based life form mean?

Tomorrow’s Exit Slip Will cover:

Energy/Chemistry Law of Conservation of Mass Oxygen Cycle Carbon Cycle

Carbon Cycle

What do these three things have in common?

Carbon

Carbon One of the most important elements Carbon can form many different molecules. Carbon serves as the main building block for

organisms. Carbon is readily found on Earth.

Where does Carbon come

from?

Carbon Dioxide in the AirCarbon Dioxide in the Air

CO2 is taken out of the air by plants through photosynthesis.

CO2 is taken out of the air by plants through photosynthesis.

Animals can’t go through photosynthesis so they get their carbon atoms from food they eat.

BOTH plants and animals release CO2 into the air through respiration BOTH plants and animals release

CO2 into the air through respiration

Decaying plants, animals, and waste after millions of years will be changed into

fossil fuels

Fossil fuels can be burned by automobiles, releasing carbon back

Carbon dioxide in the atmosphere

Burning of fossil fuels in cars and factories release carbon dioxide

Photosynthesis removes carbon dioxide from the air.

Cellular respiration releases carbon dioxide into the air
