Thursday, September 19th , 2013 ___________________________________________ Daily Objective: By the end of today I should be able to Explain what ecology is Identify the levels of organization that ecologists

study Entrance Activity: Open your book to page 63 and read the chapter mystery. What is mystery you will be trying to solve in this chapter? I. Interactions and Interdependence

Ecology The scientific study of interactions among organisms and their environment. Comes from the Greek word oikos meaning house. Natures houses come in many different sizes.

Imagine yourself sitting in your room at home. Each of the levels around you creates a bigger and bigger house s

R I T N E the All life exists

Air (atmosphere) Water Land - II. Levels of Organization To understand relationships within the biosphere, you

need to understand all the levels that life can be observed. From Smallest Largest Species, Population, Community, Ecosystem, Biome, Biosphere Biotic and Abiotic Factors

The living and non-living factors determine the survival and growth of an organism and the productivity of the ecosystem in which the organisms lives Biotic (living) all living aspects of a habitat that an organisms might interact with Abiotic (nonliving)Temperature, precipitation, wind, nutrient availability, soil type, sunlight

Biotic Abiotic SELF CHECK!! 1. What is ecology? 2. What does the word NESTED mean? 3. Order the following: Population, ecosystem, biome, species,

community 4. What is an ABIOTIC factor? 5. What is a Biotic factor? Review your biotic and abiotic connections from yesterday. One way flow of energy!! Food CHAINS and WEBS Arrows point to the movement of ENERGY!!!

Tuesday, September 23rd , 2014 ___________________________________________ Daily Objective: By the end of today I should be able to The movement of energy through an ecosystem

Entrance Activity: In looking at your homework from yesterday select one word to explain and give an example of Which word is it? What is your example? n i a m

fo Sunlight is the main source of energy for life. Does Main mean ALL???? Some types of organisms rely on energy from other sources such as inorganic chemicals Think about things at the bottom of the ocean

PRODUCERS Def: Autotrophs Organisms that use energy from their environment to make food. We refer to Autotrophs as Producers since they Produce all the

a) Energy from the Sun What is the name for the process of turning light into food? On land, plants are the

main source of photosynthesis, in the oceans it is bacteria! b) Life w/o Light What happens when Light doesnt reach Life? Is there just, no life there?

Def: Chemosynthesis a process where organisms use inorganic chemicals as their energy source. Review: What are Primary producers? II. Consumers Def: Heterotrophs

Organisms that rely on other organisms for their food and energy supply. We refer to Heterotrophs as Consumers since they have to consume other things to live. II. Consumers pg. 71

What different kinds of Consumers can there be? Herbivores

Carnivores Omnivores Detritivores - Can energy or matter ever be destroyed? III. Feeding Relationships KC: Energy flows through an ecosystem in one

direction, from the Sun or inorganic compounds, to Autotrophs, and then to Heterotrophs. Think about in terms of who-eats-who. IN YOUR NOTEBOOK Draw a food web that connects and shows the transfer of energy between at least 5 different living things.

Include pictures of each with arrows Write a paragraph under it explaining your connections HOMEWORK on a separate sheet Write a paragraph that describes how energy moves through an ecosystem. Use the following vocab words o o

o o Energy Autotroph Heterotroph Decomposer Thursday, September 25th , 2014 ___________________________________________

Daily Objective: By the end of today I should be able to Describe energy transfers throughout an ecosystem Entrance Activity: Draw the following food chain in your notebook, then label the organisms as producers, or

consumers. If they are consumers, what type of consumers are they? Also have out your packets from yesterday. III. Feeding Relationships KC: Energy flows through an ecosystem in one direction, from the Sun or inorganic compounds,

to Autotrophs, and then to Heterotrophs. Think about in terms of who-eats-who. What is energy?? Food chains A series of steps in which transfer of energy happens by eating and being eaten.

Food chain vs. Food Web Which one is more inclusive? Which gives a more accurate picture of what is really happening? They link multiple food chains together. c) Trophic Levels Each step in a Food

Chain, or Food Web, is considered a Trophic Level. As energy is passed up each level Only 10% of the energy is handed up to the next level!!! ON YOUR CAPTURE SHEET

Label each thing as autotroph or heterotroph Label each living thing with producer or consumer Label each consumer with the type of consumer it Friday, September 26th 2014

___________________________________________ Daily Objective: Same as yesterday, you do not need to rewrite it. Entrance Activity: In the picture below 1) Name the producers.

2) Name the primary consumers 3) Name the secondary consumers YOU NEED YOUR BOOK!!!!!!!!! With your grid 1. Lightly shade in each of the 100 boxes in the grid labeled producer. How many units of

energy are available to the producer? 2. Shade in the top row of boxes in the firstlevel consumer grid. How many units of energy are available to this organism? 3. Shade in only 1 box in the second-level consumer grid. How many units of energy are available to this organism? 4. Shade in one box in the inset diagram in the third-level consumer grid. How many units of energy are available to this organism?

Pyramids of energy Show the amount of energy available at each trophic level Pyramid of Biomass Amount of living matter available at each trophic level Pyramid of Numbers

Shows the number of individuals Monday, September 29th , 2014 ___________________________________________ Daily Objective: By the end of today I should be able to Explain the complex energy relationships within an ecosystem.

Entrance Activity: Please have out your notebook and a set of coloring utensils. What is the difference between a pyramid of numbers and a pyramid of biomass? Procedure 1. Go to Lowes and grab one bag of each of the 3 types of fertilizer: P enriched, N enriched, and p and n enriched 2. Get 4 of the same size pots

3. Place the same amounts of the three different fertilizers in the first 3 pots 4. Place the same amount of dirt in all 4 pots 5. Place 25 grams of grass seed in each pot. 6. Water each pot with .5 Liters of water everyday for 3 weeks. 7. Every 3 days, measure the length of the longest blade of grass for each pot 8. Record data into a table 9. Repeat steps 1-8 2 more times for more accurate results 10. Use whichever fertilizer produces the longest grass.

Silently in your notebook, write out your answer to the following questions: 1. What is the difference between a pyramid of biomass and a pyramid of numbers? 2. What unit would you use for each one? Pyramid of Biomass Amount of living matter available at each

trophic level Pyramid of Numbers Shows the number of individuals Untamed Science Tuesday, September 30th , 2014 ___________________________________________

Daily Objective: By the end of today I should be able to Explain how changes in one level of an ecosystem affects other factors in the ecosystem. Entrance Activity: Please grab a chapter mystery from the stool on your way in the door. Read through the directions and environmental report. After reading it DONT ANSWER

THE QUESTIONS, instead, try to summarize what the report has said. LAKE WASHINGTON S E L P M .

Daily Objective: By the end of today I should be able to Describe how carbon , nitrogen, and phosphorus cycle among the living and nonliving parts of an ecosystem Entrance Activity: Have out your water coloring activity and review it please

CARBON NITROGEN PHOSPHORUS Critical for life and are necessary for all things to survive. With your group

You are going to read about your cycle ON YOUR HALF SHEET List and define important vocab from your section Be able to describe the important the steps of the cycle. Wednesday, October 2nd , 2013 ___________________________________________ Daily Objective:

By the end of today I should be able to Describe how matter cycles among the living and nonliving parts of an ecosystem Entrance Activity: Please have open your book to the cycle you were in charge of starting on page 82... What different forms does your nutrient take within your cycle?

In groups of 3 Using your book, arrange and connect the squares for the nitrogen/carbon cycle Copy down your diagram into your notebook, then come up and switch Thursday, October 3rd , 2013 ___________________________________________

Daily Objective: By the end of today I should be able to Demonstrate my knowledge of ecosystems Entrance Activity: Have out your cycles that I gave you CHAPTER 3 TEST yesterday. We will finish

up with filling TOMORROW!! YOU MUST HAVE them YOURin. TEXTBOOK TODAY!! Limiting nutrient If one of the nutrients are in short supply, the ecosystem will cease to produce

In soil when the nutrients are used up, farmers can apply fertilizers which put back some of the nutrients (like nitrogen, phosphorus, calcium) In aquatic ecosystems Nutrient poor ocean: nitrogen Nutrient poor lakes and streams:

phosphorus
