Food chain
- A diagram that shows how energy flows in an ecosystem
* it only goes in One Direction
Food web
A network of complex interaction between organism
Biological pyramids
Give a visual representation of energy,numbers, & biomass
Biomass
Life stuff
Limiting factor
A factor that causes the growth of a population
-Example: lack the food, lack of space, climate change
Biomagnification / bioaccumulation
The process of increasing concentrations of a substance on a food chain
Matter
aka the ‘stuff’, or anything that has mass or volume
Cycles through the environment
•carbon•water•nitrogen•phosphorus•sulfur•
Energy
the ability to do work or make thing more.

Balancing;
Name the equation A+B->AB
Synthesis (to build, to make)
Balancing;
Name the equation AB->A+B
Decomposition ( to break, to destroy)
Balancing;
Name the equation A+BC->AC+B
Single replacement
Balancing;
Name the equation AB+CD->AC+BD
Double replacement
What does the diagram represent
[ • ]
glucose
[ ATP. ]
Carbon dioxide and water released by cellular respiration are used in photosynthesis
Which gas is removed during photosynthesis?
Carbon Dioxide
Weightlifting story …….
Which is the most likely process?
As cells run out of oxygen try switch to anaerobic respiration
What function does ATP carry out
Used to capture and transfer energy
How are cellular respiration and photosynthesis related in terms of energy
The PRODUCTS of one are the REACTANTS of the other
What do each #’s represent?
[ 1⃣ ]
🌾 🐎
[ 2⃣ ]
1-Oxygen
2-Carbon Dioxide
Autotroph
Organisms that can synthesize their own energy molecules (glucose) aka: producers
Ex: all plants
Photosynthetic bacteria
Heterotroph
Organisms that cannot synthesize their own energy molecules (glucose) and must consume (eat) at it as a result
Aka: consumers
Ex: cows, people, animals
Photosynthesis
The process by which plants and photosynthetic bacteria convert sunlight into glucose
10% Rule
Only 10% of net energy is passed onto the next level
Equation for photosynthesis
light (from he sun) + 6CO2 + 6H2O ——> C6H12O6 + oxygen6O2 + Heat
Light+carbon Dioxide +water —-> glucose+oxygen+ heat
where does photosynthesis specifically occur?
it occurs in the chloroplast (a specific organelle) of plants and photosynthetic bacteria
