- Q1An ocean ecosystem provides a habitat for many species of marine life. Which marine organism most often finds what it needs for survival on the ocean floor?TurtleOctopusSharkWhale30s
- Q2The 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 increase, as the owl population will feed on more of the shrew and wood mouse populations.They will increase, as there will be more of the green plant population for them to feed upon.They will decrease, as the wood mouse and shrew populations will feed on more of them.They will decrease, as they will feed upon each other30s
- Q3Ghost crabs are a species of crab that are a main food source for sea birds found along the Outer Banks. 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 the increase in predators.The ghost crab population will decrease because of an increase in the risk of disease.The ghost crab population will decrease because of the decrease in food sources.The ghost crab population will decrease because of the decrease in space.30s

Which statement best describes the two groups?Group 1 species live in terrestrial ecosystems; Group 2 species live in saltwater aquatic ecosystems.Group 1 species live in saltwater aquatic ecosystems; Group 2 species live in freshwater aquatic ecosystems.Group 1 species live in terrestrial ecosystems; Group 2 species live in freshwater aquatic ecosystems.Group 1 species live in freshwater aquatic ecosystems; Group 2 species live in saltwater aquatic ecosystems.30s
- Q6The image shows some organisms that live in the soil. These organisms are essential for proper growth of plants. How do these organisms benefit plants?They decrease the oxygen content of the soil.They recycle living and non-living material into soil nutrients.They loosen the soil to decrease its water content.They convert the energy from the Sun into organic matter.30s

- Q8Scientists 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 create more space at the top of the lake for the fishThe green algae will provide more food for the fishThe green algae will decrease the number of predators that eat the fishThe green algae will provide more shelter for the fish30s
