ECOLOGY - the study of interactions among organisms with each other and with environment BIOSPHERE - portion of planet where life exists


LEVELS OF ORGANIZATION

Species - individuals that can breed with one another

Population - all the individuals of the same species (ducks) in an area




What is in your backyard community area?---(Answer in the essential question area!!—you did not write this down did you? This is red!!)


Ecosystem the community plus the physical factors in an area rain light soil
Ecosystem - the community plus the physical factors in an area (rain, light, soil..)

Examples:

Rotting Log

Koi Pond

Lake

Clump of Dirt

A field

An old maple tree


Biome - large area that has a particular climate, and particular species of plants and animals that live there (tundra)


Biosphere the part of the earth that supports life
Biosphere - the part of the earth that supports life particular species of plants and animals that live there (tundra)


Ecological methods how do we study it observing experimenting modeling
Ecological methods - how do we study it? particular species of plants and animals that live there (tundra) ObservingExperimentingModeling

Models are created by humans to make predictions.


Sometimes you must be cautious in how a model interprets data
Sometimes, you must be cautious in how a model interprets data....

Imagine graphing a person's height as they age.  One could predict that by the time they were age 30, they would be 22 feet tall.   

However, the model would need to account for the slowing of growth after adolescence.

**Rewrite this in your own words


1.  A group of animals that live in the same area and can interbreed is called a (n) _____________________

2.  The study of organisms and their interactions with the environment is known as ___________________________

3.  A large area that has a particular climate and distinct plants and animals is called a ____________________________

4.  All of the different populations living in an area (plants, rabbits, coyotes...) is called the _________________________

5.  An ecosystem includes all the living and ___________ factors in an area. 

6.  The portion of the planet that can sustain life is the  ________

7.  Animals that can interbreed are called a(n) _______________


3-2 Energy Flow interbreed is called a (n) _____________________

Autotrophs (producers) - capture energy from environment and convert it into "food"

Heterotrophs (consumers) - must eat things

HerbivoresCarnivoresOmnivoresDetritivores / Decomposers


Sunlight is the main source of energy photosynthesis uses light energy to make food
*SUNLIGHT is the main source of energy* interbreed is called a (n) _____________________ Photosynthesis - uses light energy to make "food"


Chemosynthesis makes food from chemicals some bacteria synthesize food in this way
Chemosynthesis - makes food from chemicals (some bacteria synthesize food in this way)

Some bacteria live in deep ocean vents, and make their food from chemicals in those vents


FOOD CHAINS AND FOOD WEBS - illustrate the flow of energy in an ecosystem

*Note the direction of the arrows, they indicate where the energy is going when one organism consumes another.

Each step in a chain or web is called a TROPHIC LEVEL


Identify primary consumers secondary consumers tertiary consumers find the omnivore
Identify: an ecosystem Primary Consumers Secondary Consumers Tertiary Consumers Find the Omnivore.

Biogeochemical an ecosystemCycles

(biology + geology + chemical)

Matter is not used up, it is transformed, the same molecules are passed around (see images in your book)
