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? What is a sphere? Life A ball

Levels of Organization Species Population Community Ecosystem biome

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

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 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… 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?

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

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?

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)

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

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… ET: Taking Quiz 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 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

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

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

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