APES - Unit 1 Test fully solved graded A+ 2023/2024

APES - Unit 1 Test Six white-tailed deer and six sika deer were enclosed in a pasture for observation during an eight-year study in central Texas. White-tailed deer are a native species to central Texas, while sika deer are a nonnative species to central Texas. White-tailed deer feed on flowering plants and the tips of trees and shrubs but do not eat grass. Sika deer feed on flowering plants, the tips of trees and shrubs, and grass. All other grazing animals were kept out of the pasture during the study. The number of sika deer more than doubled after the eight years, while the population of white-tailed deer decreased by 50 percent. Which of the following statements best supports the results from the study? - correct answer The sika deer out competed the white-tailed deer in consuming flowering plants and shrubs In reef ecosystems, corals often have microalgae living inside them. The algae supply the corals with nutrients, and the coral give shelter to the algae. Which of the following interactions best describes the relationship between the corals and the algae? - correct answer Mutualism Which of the following best describes an example of resource partitioning in an ecosystem? - correct answer Two different bird species feed from the same oak tree; one eats acorns, and the other eats insects in the bark Which of the following describes the most likely change to terrestrial biomes resulting from warmer average global temperatures? - correct answer The global distribution of midlatitude biomes, such as grasslands and temperate rain forests, would increase. Which of the following terrestrial biomes has the highest net primary productivity? - correct answer Tropical rain forest Which of the following terrestrial biomes has the highest primary productivity per unit area? - correct answer Tropical rain forest This biome contains a nutrient-rich environment created by falling leaves and trapped organic materials from the large trees, and it provides the ecosystem service of filtering pollutants from water. - correct answer Freshwater wetlands This biome is found in shallow waters off the coastline and is Earth's most biologically diverse marine biome. - correct answer Coral reefs This freshwater biome is characterized by fast-flowing water that can originate from underground springs or runoff, which carries sediment and organic material. - correct answer Rivers Which of the following biogeochemical cycles includes the processes of buffering ocean pH and photosynthesis? - correct answer The carbon cycle Which of these is a carbon source? - correct answer Burning of fossil fuels Which represents a carbon sink that holds carbon compounds for the shortest period of time? - correct answer Vegetation Which of the following process shows the conversion of nitrogen gas into usable forms available to producers? - correct answer Nitrogen fixation Which of the following types of organisms are required to complete the nitrogen cycle, including the process of denitrification? - correct answer Bacteria The majority of the nitrogen on Earth can be found in which of the following reservoirs? - correct answer The atmosphere The diagram above best illustrates major processes in which of the following biogeochemical cycles (weathering, uplift over geological time)? - correct answer The phosphorus cycle Which of the following statements is best supported by the diagram of the phosphorus cycle? - correct answer The phosphates absorbed by animal tissue through consumption eventually return to the soil. Farmers in a suburban coastal town started using no-till agriculture, a practice that reduces soil erosion from their farmland. Which of the following long-term effects does no-till agriculture have on the ecosystem surrounding the farmland? - correct answer There will be less algal growth in the nearby ocean.
