PoNBackground Information: In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals.Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus, the forest management personnel fearedthat overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in naturalpredators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and alsincrease the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into theisland. The results of this program are shown in the following graph (below).Deer and WolfPopulation Size2500240030-282300-26242200+22whlf-20210018-16200014deer-121900-101971197219731974197519761977197819791980Describe what happened to the deer and wolf populations between 1971 and 1980.O When the wolves population was 14, the deer population was around 10O As the wolves population is increasing the deer population is also increasing.The deer and wolf populations both increased until they reached a maximum and then began to decrease until they reached aO minimum.

In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…
nd biodiversity of sites in their own community, students performed a leaf litter lab where leaf litterwas collected from two sites: one from beneath the trees in an organically managed, commercial landscapeestablished one year ago and one from beneath the trees in a nearby nature preserve that have not been trimmed ormanaged in over twenty years. The students hypothesized that there would be more insect biodiversity in the leaflitter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with alight shone on the top to drive any insects out of the litter. Species were collected in an alcohol-filled containerbelow the funnel, and the species were identified using magnifying lenses and a key
