Concept explainers
a.
To define: The plot the bead size versus the percentage of beads buried by the dung beetles.
Introduction: Large seed mimics, dispersal was equally low in secondary forest, agriculture and pasture, but was higher in agroforest. This suggests that dispersal of large seeds might suffer even in habitats that maintain a relatively complex vegetation structure.
b.
To describe: The regression line relationship in the graph and predict the percentage of beads of diameter 5mm and 14 mm that would be buried by the beetles.
Introduction: Linear regression is a model to represent the relationship between two variables by fitting a linear equation to observed data.
c.
To describe: The factors other than the size of beads of seed burial by the dung beetle, hypotheses with an experiment.
Introduction: Animals, birds and insect disperse the seeds in a distant place where the seed can germinate providing the suitable conditions.
