3 facts about the tundra
Extremely cold climate.
Low biotic diversity.
Simple vegetation structure.
Limitation of drainage.
Short season of growth and reproduction.
Energy and nutrients in the form of dead organic material.
Large population oscillations.
What is the difference between biotic and abiotic factors?
Biotic is living things in an ecosystem
Abiotic is a non living thing in an ecosystem.

Qualitative vs Quantitative
Qualitative-description of something(Jimmy is tall)
Quantitative-Numbers(Jimmy is 6’6)
What is an
Independent Variable
Dependent Variable
Control Variable
Independent-I change it/we change it
Dependent-Changes from the independent variable
Control-stays the same
What is Homeostatis
What is a Stumulus
Homeostasis is the body trying to reach equilibrium.
Stimulus is an outside force that causes the body to react
A positive feedback loop is the body …… to the stimulus. This happens during ……….
Adding
Pregnancy
A negative feedback loop is the body trying to get … of a stimulus. This happens when we ……. when we are cold.

What is the rule of Energy Flow?
10% is transferred through consumption.
90% is lost.
What is the difference between a food chain and a food web?
A food chain is only 1 way to go.
A food web is multiple food chains intertwined and interacting together.
What is Ecology
Ecology is the study of interactions between organisms and their environment.
What are demographics?
The statistics of a Population
Define Population
A group of the same species in 1 area.
What is Population size?
Total number of individuals In a population
What is Population Density
Numberof individuals in a specific area.
What is Population Distribution
Location of individuals relative to one another.
What is the first species that colonizes in a vacant habitat?
Pioneer Species
Explain how Ecological Succession works
Regrowth of a ecosystem over time.
Define Primary and Secondary Succession.
Primary-In habitats that lack fertile soil.
Secondary-In habitats that do have fertile soil.
What kind of organisms does Cellular Respiration happen in?
All living things
What process does cellular respiration always begin with?
Glycolysis
Where in the cell does Cellular Respiration take place?
Cytoplasm
What is the difference between aerobic and anaerobic respiration?
Aerobic- needs oxygen/uses oxygen
Anaerobic-Does not need oxygen
Kreb’s Cycle
Is this an Aerobic or Anaerobic process?
Aerobic meaning it needs oxygen
What organelle does the Kreb Cycle take place.
Mitochondria
What are the reactants that are needed for the Kreb Cycle to occur?
Glucose and pyruvates
What are the products that are created at the end of the Kreb Cycle
Co2 and ATP
What are the products that are created at the end of the light dependent cycle?
ATP,NADPH, O2
Calvin Cycle
What are the reactants that are needed for this reaction to happen?
What are the products that are created at the end of this reaction?
ATP, NADPH, C02
Glucose, 02
2 types of energy are essential products of photosynthesis. What are they?
ATP and NADPH
What is the importance of photosynthesis?
ToAutotrophs cannot consume food so they
go through Photosynthesis (light dependent & Calvin) to create the reactants for cellular respiration
↳ glucose & O2
Photosynthesis takes place in what organelle?
What gives this organelle its pigment/color?
Chloroplast
Chlorophyll
Lock in
Lock in
Provide the definition of photosynthesis in your own words.
Process in autotrophs that allows for food(glucose) to be made.
What is the energy source that STARTS photosynthesis?
Sunlight
What is the equation for photosynthesis?
6CO2 +6H20 +light = C6H1206 + 602
Light Dependent Reactions
What are the reactants that are needed for this reaction to happen?
H20, light
Define a Decomposer
Microscopic organism that breaks down dead or decaying organisms
What is a reactant?
Materials/Substances that go into a reaction
What is a product?
Material/Substance that comes out of a chemical reaction
What happens between a reactant and product?
Reactant then a chemical reaction happens then you get a product.
Describe Commensalism
One Organisms benefits where the other stays the same.
Describe Mutualism
Both Organism benefit
Describe Parasitism
One organism benefits positively while the other benefits negatively
Describe Predator/Prey
Bird and the worm
What is a heterotroph?
Can’t make its own food/Consumes other organisms for food
Autotroph
Makes its own food
Electron Transport Chain

How do Photosynthesis and Cellular Respiration connect?
the carbon dioxide released in cellular respiration is a reactant in photosynthesis.
