Q: What do autotrophs make?
• What is an autotroph? Types?
• What is a heterotroph? Types?
Matter and Energy
• How does matter moves through an
ecosystem?
• How does energy move through the trophic
levels?
The Carbon Cycle
The Nitrogen Cycle
What is responsible for most of the nitrogen fixation?
Succession
• What is the difference between primary and
secondary succession?
• How do you know what stage in success an
area is in?
Levels of Organization
Weather Vs. Climate
• Weather is a daily measure,
climate is long term
Greenhouse Effect
• What is it?
• What are green house gases?
• Why is this important to know?
Niche
• What is a niche?
• What is the principle of
competitive exclusion?
• Why can’t two organisms
share the same niche
Symbiotic Relationships
• Mutualism
• Commensalism
• Parasitism

Carrying capacity
Resources
• What is sustainable development?
• Renewable vs. non-renewable
Cell Structure and Function
Organelles
• Ribosomes
• Chloroplast
• Mitochondria
• Nucleolus
• Lysosome
• Cell membrane
Plants, Animals, bacteria
• Compare/contrast
prokaryotes and
eukaryotes
• What are the main
differences between
plant and animal cells
Membrane Transport
• Diffusion – the movement of molecules from a
high concentration to a low concentration
• Osmosis – diffusion of water
• Facilitated diffusion – uses a membrane
protein channel to move stuff in
• Active transport – requires energy to move
materials through a membrane transport
protein
Photosynthesis and Cellular Respiration
• Todays units will be…
– Photosynthesis
– Respiration
– Cells
• ET: Look up the
equations for photo
synthesis and cellular
respiration
– Write them in words
– Write them in symbols
ATP – How does ATP release the energy
stored in it?
• Stored chemical energy
that cells use
• Comes from the energy
store in the glucose you
get from your food
• Cellular respiration makes
atp in the mitochondria
Photosynthesis and Cellular Respiration
• How are the two connected?
• How are they similar?
• How are they different?
Photosynthesis – see book diagram ch. 8
• What: The process of making glucose using the
energy from light, water, and carbon dioxide
• Where: Happens in the chloroplast
• When: all the time – there are reactions that
require light (day) and reactions that do not
require light (night)
• How: The light dependents reactions in the
thylakoid and the light independent reactions
(Calvin cycle) in the stroma
Respiration – see book diagram ch. 9
• What: The process of making cellular energy,
ATP, from oxygen and glucose
• Where: The mitochondria
• When: all the time
• How: glycolysis (breaking glucose) – krebs
cycle – electron transport
• Fermentation?
Cells – Structure and Function
• “Euk’s have a Nuk”
• Structures: Cell membrane, cell wall, nucleus,
chloroplast, mitochondrion, ribosome,
cytoskeleton, endoplasmic reticulum, glogi)
• Membrane: Phospholipid bilayer
• Transport: Diffusion (osmosis and facilitated
diffusion), active transport
Chemistry ch. 2
• Todays topics will be…
– DNA, Genes, and Protein
Synthesis
– Chemistry of life
– Enzymes and Proteins
• ET: What are the 4
macromolecules of life?
– What are their
monomers called?
– What are their polymers
called?
Chemistry
• What are atoms made of?
• What is a compound?
•
•
•
•
DNA Structure
Made of Nucleotides: phosphate, sugar, base
Bases: guanine, cytosine, thymine, adenine
G-CAT
DNA – Chromosomes – Genes – Amino Acids Proteins

• What do enzymes do?
Ecology – chapters 3, 4, 5, 6
• Todays Units
– Population Density
– Limiting factors
• Population graphs
• Biodiversity
• sustainability
– Biological Evolution

Producers/consumers
Food chains/food webs
Carbon cycle pg. 83
Nitrogen cycle pg. 84
Population Density – Ch. 5.1
• Pg. 132 Factors that affect PD: birth rate,
death rate, and the rate of immigration and
emigration.
• Exponential Growth: rapid increase in a
population due to lac of competition for
resources
Limiting Factors – Ch. 5.2
• There are 5 limiting factors pg. 137 fig. 5-6
• What does “density dependent” mean?
Biodiversity?
• How does biodiversity contribute to
sustainability of an ecosystem? (Ch. 6)
Ch. 4 vocabulary
– Nich vs. Habitat
– Tolerance
– Competitive exclusion principle
– Keystone species: species that plays a major role
in an ecosystem
Sustainability/Sustainable Development
• Sustainable development provides for human
needs wile preserving the ecosystems that
produce natural resources
– Renewable vs. non-renewable resources
– Desertification
– Deforestation
– Biological magnification
