Some ecologists study complex interactions of animals and plants in forests.Such field research produces slightly different results for different researchers.In contrast,ecology experiments performed indoors with one organism in a terrarium usually produce results that are repeatable.What is the most likely explanation?
A)The scientific method is only useful in laboratory settings
B)It is not possible to establish a control group outside of a laboratory
C)It is easier to hold all but one variable constant in a laboratory
D)Fieldwork is evolutionary;laboratory work is experimental

In a laboratory setting, researchers are able to more easily control and manipulate variables, allowing them to isolate and study the effects of a single variable on the organism. In fieldwork, there are often many variables that are difficult to control, leading to slightly different results for different researchers. This makes it harder to achieve repeatable results in field studies.
