1. Explain what ecology is
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?

2. I. Interactions and Interdependence
Ecology – The scientific study of interactions among organisms and their environment.
Comes from the Greek word “oikos” meaning house.

3. Nature’s “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

4. All life exists Biosphere – The Level that contains the ENTIRE PLANET.
Air (atmosphere)–
Water –
Land -

5. 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

6. 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

7. Biotic
Abiotic

8. 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?

9. Review your biotic and abiotic connections from yesterday.
One way flow of energy!!
Food CHAINS and WEBS
Arrows point to the movement of ENERGY!!!

10. The movement of energy through an ecosystem
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?

11. What is the main source of energy for our Planet?
Sunlight is the main source of energy for life.
Does Main mean ALL????

12. Some types of organisms rely on energy from other sources such as inorganic chemicals…
Think about things at the bottom of the ocean…

13. PRODUCERS
Def: Autotrophs – Organisms that use energy from their environment to make food.
We refer to Autotrophs as “Producers” since they Produce all the energy that is needed by all other life!

14. 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!

15. b) Life w/o Light
What happens when Light doesn’t reach Life? Is there just, “no life there”?
Def: Chemosynthesis – a process where organisms use inorganic chemicals as their energy source.

16. Review:
What are Primary producers?

17. 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.

18. II. Consumers pg. 71 What different kinds of Consumers can there be?
Herbivores –
Carnivores –
Omnivores –
Detritivores -

19. Can energy or matter ever be destroyed?

20. 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”….

21. 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

22. HOMEWORK on a separate sheet
Write a paragraph that describes how energy moves through an ecosystem. Use the following vocab words
Energy
Autotroph
Heterotroph
Decomposer

23. Describe energy transfers throughout an ecosystem
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.

24. 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”….

25. What is energy??

26. Food chains
A series of steps in which transfer of energy happens by eating and being eaten.

27. 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.

28. 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!!!

30. 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 is.

31. 2) Name the primary consumers 3) Name the secondary consumers

___________________________________________
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!!!!!!!!!

32. 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 first-level 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?
