Because the finches eat the seeds of many of these plants, the population of birds had to compete for the seeds that were available. Most seed-eating finches prefer to eat the small, soft seeds (particularly during the drought), leaving only the large, tough Tribulus seeds for the finches not lucky enough to get to the small seeds in time.

Seed predators eating seeds and defecating in areas away from the adult plant Elephants knocking over a tree to get the leaves at the top of the tree Deer browsing all the leaves along a certain height in the forest Filter feedersarrow_forwardPine trees are coniferous trees native to most areas of the Northern Hemisphere. Pines produce seeds in the form of pine cones. In some species, pine cones open automatically upon maturation to release seeds. Other species rely solely on birds to break open the pine cones to disperse the seeds. In still others, a resin holds the pine cones closed until a forest fire melts the resin and the seeds can be released. What type of effect does a forest fire have on a pine tree population? a) Obligate b) Facultative c) Density independent d) Bioticarrow_forwardIf the null hypothesis is correct, predict how the proportion of young cacti with nurse plants will compare to the amount of available shade.arrow_forward
