Rat Islands

Assume that millions of generations ago, there was a species of rat that looked much like the picture given tothe right. Members of this species were eventually isolated on different islands as geologic change occurred.Assume that over millions of generations your rat has evolved adaptations that are an advantage in the specificisland environment described below. The purpose of this activity is to brainstorm how a species may evolvedbased on adapting to the environment and connecting species in the habitat to components in a ecosystem.Learning OutcomesExplain how adaptations help organisms survive in different environments.Identify various components of an ecosystem based on their chosen habitat.Assignment InstructionsYou will be assigned one of the island habitats based on the first letter of your last name.A-E Island 1 status:Junior Levelbalance:$6.64rating:4.829/10/2020 Order 325634950https://admin.writerbay.com/orders_available?subcom=detailed&id=325634950 2/4s.html)F-J Island 2K-N Island 3O-R Island 4S-U Island 5V-Z Island 6A handout for the assignment is attached.. Create your project in PowerPoint.Identify your habitat (or write the full description) in your PowerPoint so I know (e.g. Island 1 and copy andpaste description).Design a rat that has adapted to the environment of the island, creating a new species of rat. Describe at leastfour physical adaptations (how it looks) and one behavioral adaptation (how it acts) and why they are beneficialto the rat. You can get 2 points extra credit if you draw your rat adaptations (this doesn’t mean find a picture ofa rodent that happens to look exactly how you want your rat to be, only 1 point if drawing is a very poorrepresentation).Post photos of the island habitat, including island, water, plants, animals, etc. using real photos online. I shouldget a feeling of what your island description says.Post answers to “What’s on the Island?” based on your habitat. This means these are organisms in yourhabitat. The only liberty will be decomposers since most don’t explicitly list something that is a decomposer.What’s on the Island?Directions: Just using the organisms in your Rat Island ecosystem (including the rat), give an example of eachof the following:Note: If the organisms given don’t fit a certain category, state that and give a possible likely organism based onthe ecosystem.Producer –Consumer –Predator –Prey –Scavenger –Decomposer –Abiotic factor –Biotic factor –Limiting factor –Island HabitatsIsland 1 (Last name A-E)The island is fairly flat, with an occasional hill. The ground is soft dirt, and several species of shrubs growtowards the center of the island. There is no animal life on land; but the water is teaming with fish. The island issurrounded by a coral reef which keeps the predators out. The shore is sandy with no algal growth. Freshwater is available.Island 2 (Last name F-J)The island has a rocky shoreline. Numerous tide pools dot the island along the shore where the wave action issomewhat sheltered by rock outcrops. The tide pools host barnacles, chitons, abalone, sea urchins and crabs.Algae grows all around the island; however, it is quite sparse in the tide pools where the various animals feed.The current is quite strong along the rocky outcrops where the algae grows best. Fresh water is available. 9/10/2020 Order 325634950https://admin.writerbay.com/orders_available?subcom=detailed&id=325634950 3/4Island 3 (Last name K-N)The island is somewhat barren. A few species of cactus thrive on the bare rocks. A large cactus-eating tortoiseinhabits the island. A species of very large bird nest on the island annually. They build their nests on the rocks,and protect their eggs from the sun by standing over the nests with outspread wings. The nests are alwaysfound on the windy side of the island which is somewhat cooled by offshore breezes.Island 4 (Last name O-R)The island is an extinct volcano. Vegetation on the island changes with the altitude moving up the volcano.Grasses grow at the base. Further up the slope the grasses give way to low shrubs. Half way up, the islandbecomes quite lush; tropical plants and trees dominate the landscape. At this altitude, the island experiencesfrequent rain showers. There are two species of birds that inhabit the island. One is a raptor that preys uponthe smaller birds and the other fishes the waters approximately one mile offshore. Both nest in trees.Island 5 (Last name S-U)This island is in a polar region. Summer temperatures rarely go above 60 degrees and the winter temperaturesare below zero. The winter is long and dark, with plenty of snow. There are grassy sedges and a few smallflowers. The surface of the earth is often frozen. The island is hilly with some caves in the hillsides. Otheranimals include puffins, seals, sea lions, otters, and foxes. There are plenty of large fish off the coast.Island 6 (Last name V-Z)This island is an abandoned colonial settlement off the coast of North Carolina. There are remains of houseswith doors, windows, and cabinets. Some houses still have fireplaces and chimneys. Vegetation includesgrasses. There is an abundance of shorebirds. The water is warm and teeming with shrimp and crabs inaddition to various species of algae. The coastline of the island is rocky and contain many mollusks.
