Today’s Objectives

By the end of today, you will be able to:• recognize the role consumers play in the flow

of energy • recognize the role decomposers play in the

flow of energy

Lesson 7—Consumers

Recall our Energy Flow Diagram

Lesson 7—Consumers

• Plants do what animals cannot!– Make FOOD

• ALL animals must eat other living things– For energy– For Building Materials

Lesson 7—Consumers

• What Living Things do Animals Eat???– Plants--Herbivores– Other Animals--Carnivores– Both Plants and Animals--Omnivores

• Animals use oxygen to release energy from sugars (cellular respiration)

Clipart

Lesson 7—Consumers

• What are sugars for?– Provide fuel for movement– Used for growth– Chemical building material for living things– Can be stored for later use (how???)

Lesson 7—Decomposers

What do we know about composting???

Lesson 7—Decomposers

LAST STOP—DECOMPOSER

Lesson 7—Decomposers

• Examples of Decomposers– Bacteria

– Fungi

Many are too small to even see!!!

Clipart

Lesson 7—Decomposers

• How they Work– Can break down dead organisms into smaller

particles– Make new compounds– Create fertile soil—important building material for

new plants (PRODUCERS)

Clipart

Lesson 7—Decomposers

• Recall What Happened in the Simulation when the number of decomposers was affected!– What Happened???

ENERGY LEVEL

• How would you describe your energy level right now?– High, Medium, Low

• What types of activities affect your energy level?

• Does food affect your energy level?– Candy?

ENERGY LEVEL

HOMEWORK ASSIGNMENT• For the next 24 HOURS, record any changes in

your energy level and what may have affected your energy level

• You will record your responses and answer questions about the experience on handout

• You will be graded based on the rubric handed out
