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”

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.

animals, bacteria) interacting with one
another and their non-living environment.
Ecosystems can be of any size (e.g., forest, meadow, and log).

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

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?

Warm-up Feb. 5th Entry 9
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.

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

Biosphere Squares – Day 3
Instructions: In the Biome section of your drawing illustrate the Carbon Cycle.
You will need to include the process of photosynthesis and respiration. You will also need to include how
humans and decomposers play a role in the carbon cycle.

Biosphere Squares – Day 4
Instructions: In the community section of your drawing you will illustrate 2 Biotic relationships1.One Biotic relationship must be a type of symbiotic relationship (parasitism, commensalism, mutualism) 2.The second biotic relationship can be predator-prey relationship or competition for resources.

Ecosystem 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).

uses energy from the sun, CO2, and H20. Photosynthesis and respiration power the carbon cycle. (Rewrite the definition of respiration here:
