- FRQ 4 - (a) Use the maps provided to answer the following questions.(ii) Describe the change in the number of piping plover nests on Assateague Island between 1999 and 2009.
- FRQ 5 - (c) Use the data in the table to answer the following questions.(i) Calculate the percent of the global population that was living in more developed countries in 2018. Show your work.
- FRQ 5 - (a) Identify one factor that contributes to the high crude death rate in countries that have never experienced the changes that result from a demographic transition.
- FRQ 5 - (d) As countries change during a demographic transition, there is often a growing demand for meat in human diets. It takes an estimated XXXX(iii) Describe one environmental disadvantage associated with increasing the amount of meat in human diets, other than associated with consumption of water.
- FRQ 4 - (a) Use the maps provided to answer the following questions.(iii) Describe one likely reason for the change in the number of piping plover nests between 1999 and 2009.
- FRQ 4 - (b) Coastal species are affected by more than just natural events.(iii) Identify one human action that directly threatens coastal habitats and describe one impact on species, other than the piping plover, that use the habitat.
- FRQ 3 - (d) During a demographic transition, intensive agricultural practices used to feed a growing population can result in soil eroding from crop fields and running off into surface waters.(ii) Justify the claim made in (d)(i) by explaining and additional benefit to the proposed solution, other than preventing the erosion of topsoil.
- FRQ 4 - (b) Coastal species are affected by more than just natural events.(ii) In addition to providing habitat for piping plovers, barrier islands (and closely related landforms) are important for other reasons. Explain one way that these features help to preserve and protect the environment in
- FRQ 4 - (a) Use the maps provided to answer the following questions.(i) Identify the preferred nesting habitat for piping plovers.
- FRQ 4 - (b) Coastal species are affected by more than just natural events.(i) Special beach restrictions can help piping plovers during nesting season. Describe one restriction that could reasonably be implemented to help prevent the destruction of plover nests by human actions.
- FRQ 3 - (b) As the human population grows, forests are often clear-cut.(i) Describe one negative effect of clear-cutting forested areas.
- FRQ 2 - c. Identify EITHER one nitrogen compound OR one phosphorus compound that is considered a pollutant when released by human activity into the environment. For the compound you identified, describe the human activity and a specific environmental problem that results.
- FRQ 3 - (a) The consequences of a growing human population have been a concern since the times of Thomas Malthus when he proposed that humans could exceed their carrying capacity on Earth.(i) Describe the concept of carrying capacity for a species.
- FRQ 3 - (c) As a country industrializes, it often moves through a demographic transition. The model below illustrates the changes through the four stages of the demographic transition.(i) Based on the model, identify the stage in the demographic transition with the greatest change in crude birth rate.the greatest change in crude birth rate as stage 2.
- FRQ 2 - d. Describe ONE way in which humans have disrupted the natural cycling of carbon and TWO major environmental consequences of that disruption.
- FRQ 3 - (b) As the human population grows, forests are often clear-cut.(ii) Besides creating or expanding forest preserves, describe one mitigation strategy that humans can employ to reduce the negative impact of human population growth on forests.
- After four years of physical control efforts, the ecologists evaluate the abundance of each type of grass in the test plot. They discover that, although there is less fountain grass in their test plot than when they began, there has not been a significant increase in native hardstem lovegrass.(e) Assuming the ecologists wish to continue with an IPM approach and continue their removal efforts on the test plot for another four years, explain one modification that could be made to the research method you identified above that could alter their results.
- FRQ 1 - (b) The research findings are summarized in the graph above.(iii) Explain what the trend in relative abundance of native hardstem lovegrass and the invasive fountain grass over the12-year period implies about each species' ability to withstand drought conditions.
- FRQ 1 - (b) The research findings are summarized in the graph above.(i) Based on the data in the graph, identify the year in which the abundance of native plants versus invasive plants is nearly equal.
- FRQ 3 - (b) As the human population grows, forests are often clear-cut. (iii) Describe an additional benefit of the mitigation strategy in described in .
