•Define Ecology (Look back at Unit 1 if you need help)

•Pick a environment

•List 10 living factors and 5 non-living factors found in this environment

•Make a prediction what the term INTERDEPENDENCE means.

Imprinting- young animals

recognizing and following the first moving object they see – urge to follow is innate, what to follow is learned

Warm-up Dec. 14th #65Classical

conditioning- animal makes a connection between a stimulus and a reward or punishment; a.k.a “learning by association”

Warm-up 2/1 Entry 7

Biotic (living)relating to,

produced by, or caused by living

organisms.

Abioticnon-living chemical and physical factors in the environment,

like sun, water, rocks, temperature

Levels of the Biosphere

Biosphere: Area on earth where life exists

Biome: Areas of similar climate and vegetation

http://www.yellowtang.org/animations/organization.swf

Ecosystem: System formed by the interaction between biotic (living) and abiotic (non-living) factors in a given area.

Examples of ecosystems:

Can you think of an example?

Levels of Biosphere

Community: Interaction of biotic factors

Population: Group of individuals of the same species that occupy the same community/ecosystem

Niche: Total way of life

Includes = habitat, resource needs, symbiotic relationships,

Trophic Levels = Levels of Feeding

Producers: Produce food for themselves

Consumers: Must take in food

Herbivores: primary consumers (eat plants)

Omnivores: eat at many levels (plants and animals)

Secondary and Tertiary: may be carnivore (eats animals) or omnivore

Decomposers: break down wastes and dead organisms and return nutrients to the soil

Entry 7 2/3

Rotting Apple

Four friends argued about why an apple on the ground eventually rots away and disappears. This is what they said: Anna: “I think it is just something that happens over time”.

Selma: “I think small organisms use it for energy and building material”

Felicia: “I think the atoms and molecules in the apple break apart”.

Logan: “I think wind and water soften it, and it dissolves into the soil”.

Eli: “I think water and air rot it, then small animals come and eat the rest”.

Jack: “I think it gets old and breaks apart into pieces too small to see”.

Write out the statement from the student that you agree with. Describe your thinking. Provide an explanation for your answer.

Warm-up Dec. 17th #661. What do the arrows

Warm-Up Feb. 4th Entry 8Ecosystem

an area that contains organisms (e.g., plants,

animals, bacteria) interacting with one

another and their non-living environment.

Ecosystems can be of any size (e.g., forest, meadow, and log).

Producer An organism that obtains

its energy by using sunlight, CO2 and H20 to

synthesize

Examples include: plants and algae

Biogeochemical Cycles

Water CycleEnters through

precipitation or infiltration

Exits through evaporation or transpiration


Carbon CyclePowered by respiration and photosynthesisHumans influence by burning fossil fuels


Oxygen CycleDriven by

photosynthesis Led to

development of Ozone layer and today’s atmospher

Oxygen is consumed through respiration and decay


Nitrogen CycleBacteria are

responsible for converting nitrogen gas to usable forms

Nitrogen fixating bacteria:Nitrogen Fixation –

Bacteria chemically covert N2 to more useable forms, Examples: NH3

(ammonia) or NO3 -

(nitrate)


Denitrification – Bacteria chemically convert nitrate (NO3) back to N2

Importance of Nitrogen cycle: Nitrogen is essential for living organisms so they can build proteins

Carbon Cycle Game

As you use a colored pencil to draw arrows on YOUR carbon cycle game board, also WRITE down HOW you got there (information from the blue sheet) . This will help you later

EVERYONE should keep track of where they are on the GROUP game board (blue) and use a colored pencil to track your progress on your own game board

Use a DIFFERENT colored pencil for each cycle you complete.

ONE cycle is completed when you return back to the ATMOSPHERE

Warm-up Dec. 18th #67

Composting

Decomposers are a necessary part of a compost pile. Decomposersneed oxygen to decompose dead plants and animals. They give off carbon dioxide. Where does the carbon in the carbon dioxide come from?

Plants

You know that plants take in carbon dioxide and give off oxygen. What do you think happens to the carbon atom that was once in the carbon dioxide molecule?


PhotosynthesisA process used by plants to make their own food. It uses energy from the sun, CO2,

and H20 to make sugar (C6H12O6). Photosynthesis and respiration power

the carbon cycle. Carbon never goes away it gets

recycled in the environment and simply changes forms.

Carbon Cycle Demonstration

Draw a picture to represent the carbon cycle you saw in the demonstration.

Include the plant, pig and atmosphere. Indicate what FORM of carbon is present (carbon dioxide or sugar).

This picture should represent a CYCLE

What about NITROGEN?

Watch the video clip and write down 3 things you learn about the nitrogen cycle

Predator/Prey: Predator feeds upon another organism, Prey is organism being feed upon

Competition in animals

Competition in plants

Symbiosis: Living together in a permanent relationshipMutualism: (+,+)

both organisms benefit

textbook to write down a definition AND the three types of symbiosis

What is an INVASIVE Species??

Attack of the Asian Carp

Which graph best shows what is happening to the population of Asian carp in the mississippi watershed?

Population GrowthHow resources create specific carryingcapacities and populations are in dynamic equilibrium. Carrying Capacity:

The number of individuals an environment can support

Population Growth

Limiting factor Controls populationEx: Food, space, water

Disease AIDS, influenza, Dutch Elm disease, Pfiesteria

The Dutch elm disease fungus, Ophiostoma ulmi, grows and reproduces in the xylem of elm branches and stems. The fungus blocks water movement to tree leaves, which causes the leaves to wilt and turn brown.

What is Pfiesteria, and where is it found?Pfiesteria (fee-STEER-ee-uh) is a microscopic aquatic organism that might produce chemicals called toxins that injure or kill fish. However, these toxins have never been definitively identified. During the 1990s, Pfiesteria was blamed for fish kills on the Eastern coast from Delaware to North Carolina. It was reported to be a problem in the warmer months, usually between April and October, and only in areas where salt waters and fresh waters mix, such as estuaries, sounds, and rivers near the coast

Population GrowthJ-curve:

Period of “exponential” growth

S-curve: Population growth stabilizes as carrying capacity is reached

Population Growth J-curve: Period of

“exponential” growthS-curve: Population is limited by factors (resources) and carrying capacity is reached

Carrying capacity is the total number or organisms the environment can support
