1. Biogeochemical Cycles

2. H.B.6B.1 Develop and use models of the carbon cycle, which include the interactions between photosynthesis, cellular respiration and other processes that release carbon dioxide, to evaluate the effects of increasing atmospheric carbon dioxide on natural and agricultural ecosystems.
H.B.6B.2 Analyze and interpret quantitative data to construct an explanation for the effects of greenhouse gases (such as carbon dioxide and methane) on the carbon cycle and global climate.

4. *Energy is not the only thing that moves through the ecosystem.
ENERGY & MATTER
*Energy is not the only thing
that moves through the ecosystem.
Atoms are never destroyed only transformed.
Take a deep breath.
The atoms you just inhaled may have been inhaled by a dinosaur millions of years ago.

HYDROGEN
NITROGEN
The same molecules are passed around
again and again within the biosphere in

SOLVENT
Water is a good ____________ Many molecules dissolve in water so it provides a place for chemical reactions to happen
Water doesn’t change temperature easily so it helps with

Crash course carbon cycle

21. 6CO2 + 6H2O + sunlight & chlorophyll C6H12O6 + 6O2
ALL ENERGY
Begins with the SUN
With Photosynthesis
6CO2 + 6H2O + sunlight & chlorophyll C6H12O6 + 6O2

22. Photosynthesis
Chemical reaction where green plants use water & carbon dioxide to store the sun’s energy in glucose
ENERGY is stored in glucose
Glucose is stored as starch in plants

23. 6O2 + C6H12O6 -->  6H2O + 6CO2 + energy
CELLULAR RESPIRATION is the chemical reaction that releases the energy in glucose.It makes energy in the form of ATP.
