Learn about the study of ecology, the different levels of organization in the biosphere, how biotic and abiotic factors influence ecosystems, and the methods used to study them. Explore the flow of energy through living systems and understand the three types of ecological pyramids. Discover the cycles of matter and the importance of nutrients in ecosystems.

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
Biotic and Abiotic Factors pg. 66 • Biological influences • Physical components
What is the Biosphere? • What does bio mean? • Life • What is a sphere? • A ball
Levels of Organization • Species • Population • Community • Ecosystem • biome

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
Interdependence? • What does interdependence mean? • What things in your life are interdependent?
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?
Flow of Energy • LT: Before I leave today I will… • Trace the flow of energy through and ecosystem • Describe how consumers obtain energy and nutrients • ET: • Describe how a consumer obtains energy and nutrients? • What is another name for a consumer? • What are the different types of consumers?
Producers – Produce energy rich compounds that are later used by other organisms • Autotrophs Are • Photo Autotrophs = Photosynthesis • Chemo Autotrophs = Chemosynthesis Carbohydrates
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
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
Lets Test Our Skills! • Go to https://kahoot.it/#/ • Enter the game pin and come up with a name for you and your partner
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
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)
Ecological Pyramids • 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 • 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)
Ecological Pyramids • LT: Today I will… • Identify the three types of ecological pyramids • Trace the flow of energy through an ecosystem • ET: Taking Quiz
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
Cycles of Matter • ET: What is this a picture of? Write down some observations/questions • 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
Cycles of Matter • 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 • LT: Same as last time
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
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
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
Review of ch. 3 • Today I will… • Review concepts in ch. 3 as well as vocabulary in preparation for the test tomorrow
