Carlos is developing a new chocolate chip recipe. While testing recipes out, he notices that when he adds less and less flour to the cookie dough, the cookies get wider and spread out on the pan. What is the dependent variable in Carlos’ experiment?
how wide the cookies spread

Mia is training for a marathon. As she reads through her food & fitness tracking journal, she notices that she runs more miles on the days where she eats an apple with breakfast. What is the dependent variable in this scenario?
miles ran
300
In what trophic level dioes the snake feed at?
tertiary
300
What types of organisms go through photosynthesis?
autotrophs
300
What is the name of the energy molecule produced in CR?
ATP
400
What is the difference between extrapolation and interpolation?
Extrapolation is making an estimate outside data set, while interpolate is between two measured data points.
400
In regards to biomass and energy, why is a pyramid used to represent both?
As a pyramid goes up, it gets smaller, just as most available energy and ecosystem's biomass.

In a pond ecosystem, if the o2 levels dropped dramatically, how would this affect photosynthesis? BE SPECIFIC in regards to the two processes.
CR could not occur as much due to less o2, which would lead to less co2 being produced (raw reactant for photo).

Compare the two reactions of Photo and CR. Be specific in their relationship.
The are dependent on one another. Products to one are the reactants to another

stand for?
Dependent variable
Response/result/record
Y axis
Manipulate
Independent variable
y axis
500
What type of ecosystem could this pyramid represent? lake, forest, pond, or oak tree. How could that be possible? Elaborate for points
tree...only one producer but provides energy for many consumers. A tree could contain thousands of insects that feed birds, lizards, and larger animals.
