A team of ecologists observed feeding patterns of several populations in the desert. The energy pyramid shown below depicts the feeding patterns the ecologist observed. Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem? A. There is less energy available in the producers because their tissues are less dense than those at higher trophic levels. B. There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels. C. There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels have. D. There is less available energy in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels. CLICK HERE FOR ANSWER A diagram of a food web is shown below. Which organism receives the least amount of energy from the producers? A. Hawk B. Rabbit C. Grasshopper D. Mouse CLICK HERE FOR ANSWER The diagram below shows the cycling of nutrients in an ecosystem. The removal of which of the following groups would cause an immediate decrease in the amount of energy flowing through the system? A. Producers B. Consumers C. Decomposers D. Inorganic nutrients CLICK HERE FOR ANSWER Complete burning of plant material returns carbon primarily to the A. herbivores. B. water. C. vegetation. D. atmosphere. CLICK HERE FOR ANSWER Which of these organisms would most likely be found at the top of an energy pyramid? A. clams - a primary consumer B. sardines - a primary consumer C. sharks - a secondary consumer D. kelp - a primary producer CLICK HERE FOR ANSWER The diagram below shows the flow of carbon in a terrestrial ecosystem.  Which will most likely happen if the decomposers are removed from the carbon cycle? A. The amount of carbon dioxide in the atmosphere will increase. B. The amount of carbon dioxide in the atmosphere will decrease. C. The amount of carbon dioxide used by producers will increase. D. The amount of carbon dioxide needed by consumers will decrease. CLICK HERE FOR ANSWER In a process called transpiration, plants get rid of excess water through pores in the leaves called stomata. This excess water is then released into the atmosphere as part of the water cycle. Which of the following terms best describes how the released water enters the atmosphere? A. condensation B. precipitation C. evaporation D. capillary action CLICK HERE FOR ANSWER The framework of organic molecules essential to all organisms is composed mainly of carbon atoms. Which processes are involved in the cycling of carbon within an environment? A. photosynthesis and respiration B. evaporation and condensation C. transcription and translation D. diffusion and transpiration CLICK HERE FOR ANSWER Which of the following statements is true about natural systems? A. Consumers form the bottom levels of both the energy pyramid and the biomass pyramid. B. Producers are at the bottom level of both the energy pyramid and the biomass pyramid. C. Producers are at the bottom of the energy pyramid, but at the top of the biomass pyramid. D. Consumers are at the bottom of the energy pyramid, but at the top of the biomass pyramid.

The English language initially diffused to North America through the process of relocation diffusion.
How did English diffuse AP Human Geography?It became widely diffused because the people of England migrated with their language when they established colonies. The Jutes from Northern Denmark, the Angles from Southern Denmark, and the Saxons from Northwestern Germany.
Which of the following explains the impacts of this diffusion on Christianity in the Americas?What can explain the impact of this diffusion on Christianity in the Americas? The repeated relocation have resulted in a wide diversity of christian religious beliefs and practices.
Which of the following is an example of relocation diffusion quizlet?The diffusion of AIDS in the United States in the late-1980s is mainly an example of relocation diffusion. The westward spread of the American frontier is an example of relocation diffusion.
