Primates are frugivorous (which means they eat the fruits of plants). In doing so, primates acquire sugar-rich food and disperse the seeds, by dropping them off away from the parent plant. The likelihood of seeds surviving and germinating is much greater at a distance than it would be beneath the parent tree crown. This ecological interaction is best characterized as an example of

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment? a.one student measures the plant stem widths by using calipers. the other student measures the widths of the same plant stems again by using a different pair of calipers. b.one student measures the plant stem widths by using calipers. the other student types the measurements as they are taken into a computer spreadsheet. c.one student weighs liquids for the experiment by using a calibrated scale. the other student weighs liquids for the experiment by using a different calibrated scale.
