Which statement most likely describes what would happen to the horned owl population if all the pine trees were cut down within their habitat? The horned owl population would remain constant. The horned owl population would decrease. The horned owl population would increase. The horned owl population would become extinct. 5/17

6 Question #12 Which event would cause the tadpole population to decrease at a local pond? The lily pad population increased. The pond received a large amount of rain. The snake population around the pond decreased. The fish population increased. Question #13 The diagram shows a food web of a mountain forest ecosystem. Which change is most likely to have a positive effect on the population of the obcat in the ecosystem? increase in the population of the Mountain Lion increase in the population of the Mountain Goat decrease in the population of the Mouse decrease in the population of the Rabbit 6/17

7 Question #14 In an ecosystem, grasshoppers are the main food source for opossums. The opossums are hunted by great horned owls and gray foxes. The population of opossums is reduced due to the spread of a disease. What effect will the decrease in the opossum population have on other organisms of the ecosystem? The gray fox population will increase. The grasshopper population will increase. The grass cover in the region will increase. The great horned owl population will increase. 7/17

8 Question #15 The diagram shows a grassland ecosystem. The grasshopper population decreases due to disease. What change would most likely be observed in the populations of the beetles and snails and why? They will decrease, as they will feed upon each other. They will increase, as the owl population will feed on more of the shrew and wood mouse populations. They will decrease, as the wood mouse and shrew populations will feed on more of them. They will increase, as there will be more of the green plant population for them to feed upon. Question #16 Scientists have discovered an increase in the amount of green algae growing in Lake Waccamaw. How will the increase in the green algae population benefit the fish population of the lake? The green algae will provide more shelter for the fish. The green algae will provide more food for the fish. The green algae will create more space at the top of the lake for the fish. The green algae will decrease the number of predators that eat the fish. 8/17

9 Question #17 Ghost crabs are a species of crab that are a main food source for sea birds found along the Outer anks. Which event would most likely happen if there was an increase in the seagull population in the same area? The ghost crab population will decrease because of an increase in the risk of disease. The ghost crab population will decrease because of the increase in predators. The ghost crab population will decrease because of the decrease in space. The ghost crab population will decrease because of the decrease in food sources. 9/17

10 Question #18 The diagram shows a food web. Which organism will be affected the least by the removal of the mouse from the food web? cougar insects shrew snake 10/17

11 Question #19 The diagram shows a food web of a grassland ecosystem. What type of change in the rabbit population will be observed if the population of roadrunners decreases? The population of rabbits will increase, as coyotes would not feed on rabbits in the absence of roadrunners. The population of rabbits will decrease, as it would be the only food for coyotes in the absence of roadrunners. The population of rabbits will decrease, as rattlesnakes will feed on more grasses reducing the food for rabbits. The population of rabbits will increase, as hawks will feed on more rattlesnakes reducing the predators of rabbits. 11/17

12 Question #20 Study the bar graph that shows the number of sea turtle nests observed along North arolina s coast during a hatching season. ccording to the bar graph, which location most likely had the greatest increase in the sea turtle predator population during that time? ape Hatteras Oak Island Ocean Isle Topsail Island 12/17

13 Question #21 Which feature of a pond ecosystem makes it different from a lake ecosystem? It is surrounded by land. It is a natural body of water. It mostly has animals like fish, turtles, and beavers. It mostly has a uniform temperature from top to bottom. Question #22 The table shows characteristics of two ecosystems. Ecosystem best summarizes which land-based ecosystem? desert forest grassland mountain 13/17

14 Question #23 Which ecosystem would be best classified as a terrestrial ecosystem? estuary forest lake marsh Question #24 student listed some features of two aquatic ecosystems. Which is the correct classification of the two aquatic ecosystems based on the listed features? 1 and 2: pond ecosystem; 3 and 4: lake ecosystem 1 and 2: lake ecosystem; 3 and 4: ocean ecosystem 1 and 4: estuary ecosystem; 2 and 3: ocean ecosystem 1 and 4: lake ecosystem; 2 and 3: estuary ecosystem 14/17

15 Question #25 student listed some features of an ocean ecosystem. Which feature did the student include in the list incorrectly? Trees, shrubs, and grasses grow on the floor. Large bodies of salt water are divided by continents. Organisms like phytoplankton, crabs, sharks, and turtles are found in it. Factors like temperature, water depth, and salinity impact the types of organisms present. Question #26 student organized a few organisms into two groups. Which statement best describes the organisms in the two groups? nimals in Group live in grassland ecosystems, while animals in Group live in forest ecosystems. nimals in Group live in forest ecosystems, while animals in Group live in aquatic ecosystems. nimals in Group live in aquatic ecosystems, while animals in Group live in forest ecosystems. nimals in Group live in terrestrial ecosystems, while animals in Group live in aquatic ecosystems. 15/17

16 Question #27 This desert has a harsh climate. It averages less than 10 inches of rain a year. This desert has very hot days and cold nights, and only a limited number of plants and animals can live there. For what would desert plants most likely compete in this climate? ) light ) minerals ) space ) water Question #28 Use this food web to answer the question. To which type of ecosystem does the food web belong? ) forest ) grassland ) lake ) salt marsh 16/17

17 Question #29 Where in a forest ecosystem would the largest amount of earthworms most likely be found? ) inside the bark of trees ) inside flowering plants ) mixed in the rocks of streams ) mixed in decaying leaves and soil Question #30 n ecosystem can support many different organisms. How is this possible? ) Organisms occupy different niches in an ecosystem. ) Organisms compete for resources in the ecosystem. ) Organisms have no relationships in the ecosystem. ) Organisms have to have individual ecosystems. 17/17
