Which of these factors do you think effects the distribution of individuals in a population? Choose All That Apply O Mating behavior Dispersal of offspring O Availability of resources Social interactions O small size

Use Verbal description of results from graph and then Interpret the graph for Exclusive range sccenario in foraging lab. The interpretations must include  Were the results expected and Did they support the hypotheses? If so, state the biological significance of the results from graph. If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis:  In the context of exclusive ranges, the foraging times would be significantly affected by the introduction of competition, as opposed to territoriality. This increased competition was expected to deplete food resources and result in harassment by competing individuals.
