Life Abounds
Consume or be Consumed!& Decomposers
http://quest.arc.nasa.gov/projects/astrobiology/astroventure/index.html
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
• 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?
