Vocabulary
something that can control or limit a population
limiting factor
plants/producers
Which organism on food web 1 is the producer?
2 (the tree)
What are the outputs of cellular respiration?
co2 and h2o and energy (ATP)
an organism that affects all other organisms in the food web
keystone species
an organism that gets its energy by eating another organism
consumer/heterotroph
What would happen to the fox population if a new predator was introduced to the ecosytem that only ate rabbits?
The fox population might decrease at first because it would be in competition with the new predator, but it would probably just eat more squirrels and snakes.
What are the inputs of photosynthesis?
co2 and h2o and sun energy
the maximum number of organisms a given ecosystem can support
carrying capacity
10%
What would happen to the ecosystem if all of the trees were infected with a parasite?
Since there is only one producer in the ecosystem, the entire system would collapse because this is the food source that fuels the rest of the ecosystem.
What would happen to a mouse in a closed system and why?
a mouse would die because he would run out of oxygen and would not be able to do cellular respiration.
non-living
abiotic
What happens to the other 90% of energy that is not transferred to the heterotroph?
It is lost as heat to the atmosphere
Based on the chipmunk graph on your handout, which area on the graph specifies the carrying capacity of the chipmunk population?
A
What would happen to a mouse and plant in a closed system?
The mouse and plant would be ok because the mouse gives off the co2 for the plant and the plant gives off the o2 for the mouse.
an organism that can produce its own food (another name for producer)
autotroph
Where does all the energy for the food web begin?
The sun
Which point on the chipmunk graph indicates a decline in the carrying capacity of the chipmunk?
between C and D
How are cellular respiration and photosynthesis related?
the products of photosynthesis are the reactants of cellular respiration and vice versa.
