1. What is Ecology? Today I will…
Describe the study of ecology
Describe the levels of organization of the biosphere
Explain how biotic and abiotic factors influence an ecosystem
Describe the methods used to study an ecosystem
Entry task: Identify all the living and non-living parts in the following picture

2. Biotic and Abiotic Factors pg. 66
Biological influences
Physical components

3. What is the Biosphere? What does bio mean? What is a sphere? Life
A ball

4. Levels of Organization
Species
Population
Community
Ecosystem

6. Ecological levels of organization foldable
The following should go in each square: Working from largest level (the biosphere) to smallest level write…
The name of grouping
The definition
An example. Your example could be a picture

7. Interdependence? What does interdependence mean?
What things in your life are interdependent?

8. Lets Review…

9. Energy, Producers, and Consumers
LT: Today I will…
Define primary producers
Describe how consumers obtain energy and nutrients
Trace the flow of energy through living systems
ET: What is a food web?

10. Flow of Energy LT: Before I leave today I will… ET:
Trace the flow of energy through and ecosystem
Describe how consumers obtain energy and nutrients
Flow of Energy
ET:
Describe how a consumer obtains energy and nutrients?
What is another name for a consumer?
What are the different types of consumers?

12. Producers – Produce energy rich compounds that are later used by other organisms
Carbohydrates
Autotrophs Are
Photo Autotrophs = Photosynthesis
Chemo Autotrophs = Chemosynthesis

13. Food Web The flow of energy
Consumers – organisms that rely on other organisms for energy and nutrients
Food Web
Heterotrophs
Herbivores - bunny
Carnivores - Snake
Omnivores - Bear
Detritivores – Earth worms: Chewing or grinding
Decomposers – fungi: Chemically breaking down
Scavengers – vulture
The flow of energy
What is this diagram called?
What is it representing/showing?

14. Can we trace the flow of energy?
Use the cards and your dry erase to correctly direct the flow of energy between the organisms
Record your results on your capture sheet

15. Lets Test Our Skills! Go to https://kahoot.it/#/
Enter the game pin and come up with a name for you and your partner

16. Ecological Pyramid Pogil
Today you will start your group pogil activity
We will use these questions to facilitate our learning and discussions for the next couple of class periods
You will revisit your role and asses your progress throughout the activity

17. Ecological Pyramids LT: Today I will…
Identify the three types of ecological pyramids
Trace the flow of energy through an ecosystem
ET: What are the 3 types of ecological pyramids? (use your book to help you)

18. Energy – show the amount of energy available at each level
Biomass – show the amount of living/organic matter at each level
Numbers – show the number of organisms at each level
Ecological Pyramids

19. Ecological Pyramids LT: Today I will…
Identify the three types of ecological pyramids
Trace the flow of energy through an ecosystem
ET: What is included in a pyramid of numbers (see your pogil)

20. Ecological Pyramids LT: Today I will… ET: Taking Quiz
Identify the three types of ecological pyramids
Trace the flow of energy through an ecosystem
ET: Taking Quiz

21. Ecological Pyramids LT: Today I will…
Identify the three types of ecological pyramids
Trace the flow of energy through an ecosystem
ET: Review your pogil. Get ready to ask questions that you still have
Energy
Numbers
Biomass

22. Cycles of Matter LT: Today I will…
Describe how matter cycles among the living and nonliving parts of an ecosystem
Describe how water cycles through the biosphere
Explain why nutrients are important in living systems
Describe how the availability of nutrients affects the productivity of ecosystems
ET: What is this a picture of? Write down some observations/questions

24. Cycles of Matter LT: Same as last time
ET: Using what you have read about the water, carbon, nitrogen, and phosphorous cycles, think of something you do, or that you see done regularly, that could disturb or is part of each of these cycles – you will use this later in class

25. Cycles of Matter
Unlike the one-way flow of energy, matter is recycled within and between ecosystems
Biological, geological, and chemical aspects of the biosphere are connected
Water
Carbon
Nitrogen
Phosphorous

26. Organic Compounds

27. Carbon

28. Nitrogen

29. Phosphorus

30. Limiting Nutrient
A single nutrient that is scarce or cycles very slowly.
Ex. Phosphorus is often a limiting nutrient that comes in waves of run-off from fertilizer. This flush of nutrients causes fast reproduction causing algal blooms

31. Homework Assignment: Due Wednesday
Explain how a change in each of these would affect the health of the ecosystems in the diagram
Carbon cycle: If ___________ were to happen it would cause _____________________ because
Nitrogen cycle: if ___________ were to happen it would cause _____________________ because
Phosphorus cycle: if ___________ were to happen it would cause _____________________ because

32. Review of ch. 3 Today I will…
Review concepts in ch. 3 as well as vocabulary in preparation for the test tomorrow
