Teacher Suggestion:

1. Teacher Suggestion: • Have the students take notes over the power point using the combination notes format. See the combination notes document in Unit 1 activities on COL for an example. • Have them number their slides in their notes. (this is useful for identifying where they found the correct answer when doing test corrections) • After taking notes they should complete their visual representation of the words and phrases in their notes on the right side of the paper and a summary at the bottom. Suggested visual representation for this presentation: Tree Map – Components of an Ecosystem (Biotic and Abiotic) Have the students classify 15 things that they can find in the ecosystem outside their house into either part.

2. Ecology The study of the interactions that take place between organisms and their environment

3. Ecosystem • The components of an Ecosystem are all of the living things (biotic factors) and nonliving things(abiotic factors) that interact in a particular area.

4. Abiotic Factors Soil Rocks Water Air Sun Temperature Biotic Factors Plants Animals Fungi Bacteria Things that were once living are also biotic factors. Biotic and Abiotic Factors

5. Bacteria Decaying leaves Sunlight Wind Frog Rose Mushroom Dead grass Temperature Rocks Dandelions Mountain Oak tree Acorn Squirrel River CPS Quiz-Choose A. Biotic Factor or B. Abiotic Factor

6. 2. Habitat • The place where an organism lives that provides the type of food, shelter, moisture and temperature needed for survival.

7. 3.Species • A group of similar organisms that can mate and produce fertile offspring.

8. Variation • Not all organism’s within a species are exactly alike. • The differences between organisms of the same species are called variations. • Sometimes one variation is more helpful to another, (sharper teeth, different colors). • Most of the time variations begin as a mutation. • http://www.butterflies.org/lvstk.cfm?lvstkID=7

9. Adaptation • The organism’s with that variation have a better chance of surviving and producing offspring. • A characteristic that helps an organism survive in it’s environment and reproduce is called an adaptation.

10. 4. Niche • An organism’s niche is it’s unique role in it’s environment. Their niche includes the types of food it eats, how it gets it’s food, how it avoids danger and what special conditions it needs to survive and reproduce. • Basically an organisms Niche is everything it does.

11. 5. Population • All of the organisms that belong to the same species living in a community

12. 6. Community • All of the populations of different species that live in an ecosystem

13. All of the organisms that belong to the same species living in a community The place where an organism lives that provides the type of food, shelter, moisture and temperature needed for survival. All of the populations of different species that live in an ecosystem An organism’s unique role in it’s environment. This includes the types of food it eats, how it gets it’s food, how it avoids danger and what special conditions it needs to survive and reproduce. Habitat Niche Population Community CPS Quiz

14. The differences between organisms of the same species A group of similar organisms that can mate and produce fertile offspring A characteristic that helps an organism survive in it’s environment and reproduce Species Variation Adaptation CPS Quiz

15. 7. Energy Roles • An organism’s energy role is determined by how it obtains energy and how it interacts with the other living things in its ecosystem. • Producer– an organism that can make it’s own food. • Consumer– an organism that gets energy by feeding on other organisms • Decomposer – breaks down wastes and dead organisms and return the raw materials to the environment.

16. 9. Producer • Source of all the food in an Ecosystem • Most get their energy from the sun and turn it into food through photosynthesis. • Most producers are plants, but some are bacteria and algae

17. 10. Consumers • Herbivores - Only eat plants • Carnivores - Only eat animals • Omnivores - Eat plants and animals • Scavengers - Feed on the bodies of dead organisms • Decomposers: Organisms that bring about decay of dead organisms: examples are: fungi, mushrooms

18. 11. Biome • A large geographic area with similar climates and ecosystems. • Examples: • Tundra • Desert • Tropical rain forest

19. Energy Movement • Food chain: The transfer of energy through a community of organisms. Simple food chain – a series of producers and consumers in which energy is passed on when the consumer eats a producer or another consumer. • Food web: A complex feeding system which contains several food chains. This documents that consumers eat more than one type of food. • Energy always moves in the direction of the arrows. http://www.sciencebob.com/lab/q-web-chain.html

20. Only about 10% of energy is transferred to the next level. 90% is used for the organism’s life processes or lost as heat to the environment. 3rd level consumer 2nd level consumers 1st – level consumers Producers Energy Pyramids Used to show the amount of energy that moves from one feeding level to another in a food web.

21. An organism that gets energy by feeding on other organisms Where most producers get their energy. An organism that can make it’s own food. breaks down wastes and dead organisms and return the raw materials to the environment. Feeds on the bodies of dead organisms Producer Consumer Decomposer Sun Scavenger CPS Quiz
