Thursday – 9/17 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

Is made up of… The Biosphere Is made up of… Species Ecological Levels of Organization

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?

Lets Review…

Energy, Producers, and Consumers Friday 9/18 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 9/21 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 Heterotrophs – Herbivores - bunny – Carnivores - Snake – Omnivores - Bear – Detritivores – Earth worms: Chewing or grinding – Decomposers – fungi: Chemically breaking down – Scavengers – vulture Food Web 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 Enter the game pin and come up with a name for you and your partner Game Pin:

POGIL / POGIL ROLES Write your job at the top of your pogil paper PROCESS ANALYST – o bserves group dynamics and behavior with respect to the learning process QUALITY CONTROL – Guides consensus-building, verifies all individual are completing their questions at the appropriate level FACILITATOR – Keeps the group on task, manages time, makes sure all voices are heard SPOKESPERSON – communicates group questions and clarifications with the teacher or other groups, presents conclusions of the group to class

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 – 9/22 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

STOP AFTER Q12 GROUPS GET READY TO SHARE YOUR RESPONSES

Ecological Pyramids – 9/23 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)

STOP AFTER Q18 BE READY TO SHARE YOUR RESPONSES

STOP AFTER Q25 BE READY TO SHARE YOUR RESPONSES

Ecological Pyramids – 9/24 LT: Today I will… – Identify the three types of ecological pyramids – Trace the flow of energy through an ecosystem ET: Taking Quiz Substitute teacher today. Working on POGIL

Ecological Pyramids – 9/25 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 9/28 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 9/29 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 Monday

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

Organic Compounds

Carbon

Nitrogen

Phosphorus

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

Wednesday 9/30 – Review of ch. 3 Today I will… – Review concepts in ch. 3 as well as vocabulary in preparation for the test tomorrow
