Faculty Data Interpretation( the HW is just answer 5 Questions (small paragraphs) basted on two graghs about spiders - Assignment Example A small number of gum-footed threads would reduce the chances of the spider capturing its prey. The threads observed in figures 1 and 2 shows that the house spider employs the optimal foraging theory in capturing its prey. Well-fed spiders spin a heavier mass of silk. It costs more in terms of energy and time to spin a web. A starving spider does not have the energy that is required to spin a web. In figure one, well-fed spiders spin heavier webs than starving ones. However, the spider has to capture prey or it will die. To avoid starvation, it would increase the number of sticky gum-footed threads to avoid death. The sticky gum footed threads offer it a higher chance of catching prey with less energy expended. This phenomenon is observed in figure 2 where the starving spiders spin more sticky gum-footed threads than the well-fed spiders. Arthur, Christopoulos and Harvey, Motulsky.
