Unit 3 Biology:How do organisms get their energy
Photosynthesis
Two parts:
Light Independent Reactions
Calvin cycle
Steps
G3p+ATP is used to create the sugar RUBP.
4.Regeneration
G3P is used in many things around the plant
3.Carbohydrate formation
Get turned back into NADP+ and ADT
Using NADPH and ATP
3 PGA is turned into 6 G3P
2.Reduction
Sugar is turned into two 3 carbon strands called 3 PGA
Using rubisco
C02 combined with Rubp sugar
1.Carbon fixation
Light dependent
Psii
the first link in the chain of photosynthesis.
captures photons
Uses the energy to extract electrons from water molecules
Releases oxygen
psi
uses light energy to energize electrons
Makes NADP to NADPH
ATP Synthase
Make Adt into ATP using the electrons
Create ATP, NADPH, and oxygen using Light, Nadp+, water, and ADP
Cellular respiration
Glycolysis
2 glucose and ATP are used to create pyruvate,
2 ATP is created
NAD+ is transformed into NADH
Pyruvate oxidation
Pyruvate is turned into acetyl CoA
Anaerobic respiration.
Krebs cycle
Acetyl CoA combines with a 4-carbon molecule
Produces:
Carbon dioxide
2FADH
2NADH
2ATP
ETC
FADH and NADH drop off electrons at ETC
Electrons are then used in ATP synthase to create massive amounts of ATP.

Energy pyramids
Types of animals for each trophic level:
Trophic level 1: Producers
Gain energy from sun
Start
100% energy
Decomposers
Decompose the dead animals
Trophic level 2: Primary consumer
Eat Producers
10% energy
Trophic level 3: Secondary consumers
Feed on Primary consumers
1% energy
Trophic level 4: Tertiary producers
Feed on Secondary Consumers
Can also feed on Primary consumers and Producers.
.1% energy
Limits of population
Carrying capacity
1) exponential growth
2) overshoot
3) decline
4) recovery
5) carrying capacity.
Resources and space
Not enough resources could result in deaths
Space needed to do certain activities(Plant roots)(Mate and Lay Eggs)
