locals harvest timber from a publicly owned forest faster than the trees can be reproduced. after only a short period of time the forest is entirely depleted of mature trees. this is an example of

conducting an experiment in the field (compared to in a lab setting) often results in a lack of

• controlled variables

• independent variables

• dependent variables

• limiting nutrients

• an open system

Edgar wants to see if attaching a limestone filter to the tailpipe of his truck reduces the CO2 emissions. He drives the same route to and from school and work with the filter for 7 days and then does the same thing without the filter. He purchased a device that measures the CO2 output that is attached to his vehicle for both weeks. What is the independent variable for this experiment?

• limestone filter vs. no filter

• CO2 emissions

• route and distance driven

• average temperatures during week 1 vs week 2

Ernestina wants to conduct an experiment on the impacts of lawn fertilizer runoff on her neighborhood retention pond. What would NOT be a recommended controlled variable/constant for the proposed experiment

• same pond tested

• same temperature during sampling

• same test kit used for both trials

• same amounts of fertilizer used for trial 1 vs trial 2

• same nutrients in the fertilizer(s) tested

A hypothesis should include each of the following words (select all that apply)

• if

• then

• because

• aforementioned

• hereby

why aren't energy transfers 100% efficient?

• the energy "lost" is converted into a lower-quality energy (example: lost as heat)

• they are 100% efficient in machines, but not in animals

• the animal saves some energy up before it allows itself to be eaten by the organism on the next trophic level

• all of these are correct
