PhotosynthesisPhotosynthesisEQ: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 Photosynthesis is like BakingBakingMake 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)

PhotosynthesisPhotosynthesisPhotosynthesis is a chemical

reaction just like cake! What do we need for

photosynthesis?

Ingredients:◦Water◦Carbon Dioxide

ENERGY!!◦Sunlight

Sugar is like a batterySugar is like a battery

When an organism needs energy, they can burn sugar.

OxygenOxygenWhen a plant makes sugar there

is leftovers.

Very important for us!Making sugar leaves extra

oxygen which plants breathe out. We breathe in.

ReviewReviewWhat 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
