Photosynthesis
What organisms undergo photosynthesis?
producers (plants)
What organisms undergo cellular respiration?
ALL OF THEM
What direction does energy flow in a food chain? (How do the arrows point)
Producer -> Primary Consumer -> Secondary Consumer -> Tertiary Consumer
All arrows point to detrivore!!
What is mutualism? Give an example of a mutualistic relationship
When both organisms benefit (+/+)
Each zooplankton has 10 ug of plastic
A squid eats 5 zooplankton
An albatross eats 5 squid
How many ug of plastic are in the squid?
250 ug
Where does photosynthesis occur?
Chloroplast
Where does cellular respiration occur?
Mitochondria
A fox eats a rabbit that eats a flower. What are the trophic levels of the flower, rabbit, and fox?
Flower- P
Rabbit- PC
Fox- SC
What is parasitism? Give an example of a parasitic relationship.
When one organism benefits and the other is harmed
Each zooplankton has 2 ug of plastic
A squid eats 4 zooplankton
An albatross eats 6 squid
How many ug of plastic are in the squid?
48 ug
What are the reactants of photosynthesis? Chemical symbols including numbers AND words
Sunlight (solar energy), Carbon Dioxide (6 CO2), Water (6 H2O)
What are the reactants of cellular respiration? Chemical symbols including numbers AND words
Glucose (C6H12O6) and Oxygen (6 O2)
What is a detrivore?
An organism that eats decaying organisms
Ex: mushroom, earthworm
What is commensalism? Give an example of a commensalistic relationship
When one organism benefits and the other is UNAFFECTED
Each zooplankton has 7.5 ug of plastic
A squid eats 17 zooplankton
An albatross eats 3 squid
How many ug of plastic are in the squid?
382.5 ug
What are the products of photosynthesis? Chemical symbols including numbers AND words
Glucose (C6H12O6) and Oxygen (6 O2)
What are the products of Cellular Respiration? Chemical symbols including numbers AND words
Carbon Dioxide (6 CO2), Water (6 H2O), and ATP (cellular energy)
Calculate the energy at each trophic level if the producer has 10,000 J of energy. When you draw an energy pyramid, which trophic level is at the bottom of the pyramid?
Producer: starts at bottom- 10,000 J
PC- 1,000 J
SC- 100 J
TC- 10 J
Caterpillars feed on the leaves of the nettle and are protected from predators by the stinging hairs on the plant. In return, the caterpillars help to pollinate the nettles as they feed on them.
What type of symbiotic relationship is this?
Mutualism
Surprise! It's a characteristic of life question. What are the definitions of biotic and abiotic? Give an example of each
Biotic- living
Abiotic- non-living
How would one decrease the rate of photosynthesis? Explain
Decrease carbon dioxide, water, and/ or sunlight because they are the reactants
How would one decrease the rate of cellular respiration? Explain
Decrease oxygen and/or glucose because they are the reactants
Calculate the energy at each trophic level if the secondary consumer has 50 J of energy. When you draw an energy pyramid, which trophic level is at the top of the pyramid?
Producer: starts at bottom- 5,000 J
PC- 500 J
SC- 50 J
TC: at the top- 5 J
A tree provides shelter and protection to the bird without getting significantly harmed or affected by the bird.
What type of symbiotic relationship is this?
Commensalism
Surprise! It's actually a photosynthesis/ cellular respiration question!
What would happen to the rate of cellular respiration if the amount of sunlight plants get goes down. Why?
The rate of CR would decrease. The rate of photosynthesis would decrease because sunlight is necessary for photosynthesis, which means they will produce products (oxygen and glucose) slower. Because the products of P are the reactants of CR, CR would decrease proportionally as well.
