PhotosynthesisEQ:What resources do plants need to make food?How does plants and animals help each other?Warmup Review:What does an energy pyramid represent? Why does energy run out by the time it gets to a 3rd level or 4th level consumer?
Photosynthesis is like BakingMake a cake
Ingredients◦ Eggs◦ Milk◦ Flour
Oven/PanHeat
◦ Gives energy◦ Cake mix turns
to cake.
Make Sugar(glucose)
Ingredients◦ Carbon Dioxide◦ Water
Plant/ChlorophyllSunlight
◦ Gives energy◦ Ingredients are
turned into SUGAR!!(glucose)
PhotosynthesisPhotosynthesis is a chemical
reaction just like cake! What do we need for
photosynthesis?
Ingredients:◦Water◦Carbon Dioxide
ENERGY!!◦Sunlight
Sugar is like a battery
When an organism needs energy, they can burn sugar.
OxygenWhen a plant makes sugar there
is leftovers.
Very important for us!Making sugar leaves extra
oxygen which plants breathe out. We breathe in.
Oxygen burnsWhy do we need oxygen?
To BURN SugarWe burn sugar for energy.
Burning sugar makes Carbon Dioxide
Carbon DioxideWho needs carbon dioxide?
Why do plants need carbon dioxide?
How do animals help plants?
How do plants help animals?
Summary
Sunlight
Carbon Dioxide
Water
Oxygen
Sugar
Carbon Dioxide-Oxygen Cycle
ReviewWhat two chemicals do plants need
to make sugar?What do plants need from sunlight to
be able to turn chemicals into food?What do plants breathe out when
they are done with photosynthesis?How do animals get the sugar?Why do animals need the sugar?What do the animals release when
they breathe out?
Draw a diagram with a plant and an animal. Include the following things. ◦Show the plant taking in Carbon
Dioxide and water, Sunlight◦Show what the plant releases◦Show what the animal takes in◦Show what the animal releases. ◦Show sugar
