Photosynthesis
November 12 & 13
Do Now• Turn in “Yellowstone Food Web Analysis”• Begin working on today’s warm-up on your
tracker
What do plants need to survive?
Food Webs & Energy Flow Concept Check
Objective
• Diagram the inputs and outputs of photosynthesis
By the end of class, students will be able to:
Food webs show flow of energy
Organisms that eat other organisms for food are called….?
Heterotrophs or Consumers
Organisms that make their own food are called ….?
Autotrophs or Producers
Where do plants get their energy?
Important!• Plants do not make their own energy; they
capture energy from the sun!• Plants do not make their own energy; they
capture energy from the sun! • Plants do not make their own energy; they
capture energy from the sun!
Photosynthesis• The process by which algae and plants use
sunlight energy to make SUGAR.
Photosynthesis• Photo = “Light”• Synthesis = “To make”• Photosynthesis = “To make with light”
Photosynthesis takes place in structures called chloroplasts
What are the two steps of photosynthesis?
• Step 1: Collect light energy• Step 2: Use energy to make glucose
Step 1: Collect light energy
A pigment called chlorophyll absorbs
light energy from the sun
Step 2: Use energy collected by chlorophyll to make sugar (glucose)
C6H12O6• 6 carbon atoms• 12 hydrogen atoms• 6 oxygen atoms
The carbon comes from carbon dioxide (CO2)
CarbonOxygen
Oxygen
Carbon dioxide enters through holes in the leaf called stomata
The hydrogen comes from water (H2O)
Oxygen
HydrogenHydrogen
Water enters through the
roots and travels to the
leaves through tubes called
xylem
Water + Carbon Dioxide + Energy Sugar + Oxygen
+ + +
INPUTS OUTPUTS
Glucose is transported to the roots for storage
Oxygen is a waste productIt exits through the stomata

Food webs in the deep ocean• Sunlight only penetrates 200 meters of water
Food webs in the deep ocean
• Most deep-sea life is indirectly dependent on sunlight
Food webs in the deep ocean• But not all of it!
Chemosynthesis
• Energy from breaking down chemicals from volcanic vents
Exit ticket• Why is it wrong to say “plants make energy.”
