The movement of a nutrient among the Earth, living organisms, and the atmosphere.
Nutrient cycle
100
All biotic and abiotic factors that make up one environment.
ecosystem
100
Thin, flexible barrier that regulates what enters and exit the cell (semi-permeable)
cell membrane
100
New species forms due to the population being separated by a new physical barrier in the environment
Geographic isolation
200
what we use or change to produce results
independent variable
200
the process in which all living organisms release carbon dioxide back into the atmosphere?
Cellular respiration
200
Capture sunlight and turn it into energy that can be used by other organisms.
autotrophs
200
regulation of one’s internal environment to maintain conditions suitable for survival
homeostasis
200
living organisms only come from other living organisms
Biogenesis
300
what we measure
dependent variable

nitrogen gas --> ammonia
nitrogen fixation
300
eats tertiary consumer
Quaternary Consumer

Ms. Smith wants to test if her students’ writing skills will improve by listening to more pop music. One set of students won’t listen to pop music, the second set will listen to 30 minutes of pop music every day, and the third set will listen to 50 minutes of pop every day. All sets of students must submit writing assignments at the end of every week. What are the independent & dependent variables?
Independent: how much pop music Dependent: writing skills
400
the building block of organic molecules that make up organisms
Carbon
400
Get food energy by breaking down dead organisms into detritus. Also called Decomposers
Saprotrophs
400
Keeps phospholipids from sticking together and assists with moving needed nutrients in and out of the cell

Mr. E wants to know if eating Flamin’ Hot Cheetos will help him lose weight. He gathers twelve students with similar weight and weighs them before beginning the experiment. Mr. E has six of the students eat Cheetos with lunch three times a week for one month. The other six students eat exactly the same food & beverages for lunch as the first group but without any Cheetos. After one month, Mr. E weighs all twelve students and records data. what is the independent and dependent variable?
Independent: cheetos Dependent: weight
500
What processes is involved in both the Carbon Cycle and Oxygen cycle?
photosynthesis and respiration
500
Series of organisms dependent on each other for food energy.
Food Chain
