Mr. Vin's Surprise Bin
100
Give an example of a heterotroph
any animal, fungi, bacteria
100
How do plants get water?
Through their roots
100
What are the two kinds of cellular respiration and which provides more energy?
aerobic and anaerobic; aerobic
100
Where does energy from the food chain come from?
the sun
100
What cells undergo cellular respiration?
all!
200
Define autotroph
organisms that make their own food
200
How do plants take in CO2?
Through the stomata
200
Why do we feel sleepy when we are in a classroom with all doors and windows closed?
O2 decreases and CO2 increases as we inhale and exhale
200
What level (primary, secondary, tertiary) consumer is the rabbit?
Primary
200
What kind of fermentation do humans do?
lactic acid
300
What are the 4 types of consumers?
herbivore, carnivore, omnivore, scavenger
300
What is the balanced equation for photosynthesis?
6 CO2 + 6 H20 -> 6 O2 + C6H12O6
300
What is the balanced equation for Cellular Respiration?
6 O2 + C6H12O6 -> 6 CO2 + 6 H20 + ATP
300
As trophic levels increase, _____ decreases
biomass
300
What moves through the xylem?
water
400
Define chemosynthesis
making food from chemicals
400
What are the products of a light-dependent reaction?
Main: ATP, NADPH
Waste: O2
400
What is the purpose of fermentation in anaerobic cellular respiration?
It provides NAD+ to keep glycolysis going
400
What is the 10% rule?
10% of energy moves up each trophic level
400
Why must chemical equations be balanced?
Matter (atoms) cannot be created nor destroyed
500
What are the 2 ways producers can make food?
photosynthesis, chemosynthesis
500
What are the products of a light-independent reaction?
Main: Glucose
Waste: ADP, NADP+
500
What happens in each of the 3 steps of aerobic cellular respiration?
Glycolysis
Citric Acid/Krebs cycle
Electron Transport chain
break glucose in half
breaks pyruvate down even further and makes electron carriers
electron carriers make LOTS of ATP
500
Is it more sustainable to eat at a lower trophic level or a higher trophic level? Why
Lower
500
Why do leaves change color in the winter?
Lack of light means the (green) chloroplasts die, leaving other pigments to show through
