Environmental Issues Unit 2: Populations Chapter 8 – Understanding Populations Terminology population density dispersion growth rate reproductive potential exponential growth carrying capacity 8-1: 8-2: niche competition predation parasitism mutualism commensalism symbiosis Describe the three main properties of a population Describe exponential population growth Describe how the reproductive behavior of individuals can affect the growth rate of their population Explain how population sizes in nature are regulated Explain the difference between niche and habitat Give examples of parts of a niche Describe the five major types of interactions between species Explain the difference between parasitism and predation Explain how symbiotic relationships may evolve Research Project…possibility! Presentation on either an endangered species or an invasive species. Environmental Issues Unit 2: Populations Chapter 9: The Human Population Terminology demography age structure survivorship fertility rate migration life expectancy demographic transition 9-1: 9-2: infrastructure arable land urbanization least developed countries Describe how the size and growth rate of the human population has changed in the last 200 years Define four properties that scientists use to predict population sizes Make predictions about population trends based on age structure Describe the four stages of the demographic transition Explain why different countries may be at different stages of the demographic transition Describe three problems caused by rapid human population growth Compare population growth problems in more-developed countries and less developed countries Analyze strategies countries may use to reduce their population growth Describe worldwide population projections into the next century Environmental Issues Unit: Populations Chapter 10: Biodiversity Terminology Biodiversity Gene Keystones species Ecotourism Endangered species Threatened species Exotic species germ plasm Endangered Species Act habitat conservation plan Biodiversity Treaty poaching endemic species 10-1: Describe the diversity of species types on Earth, relating the differences between known numbers and estimated numbers List and describe three levels of biodiversity Explain four ways in which biodiversity is important to ecosystems and humans Analyze the potential value of a single species 10-2: Define and give examples of endangered and threatened species Describe several ways that species are being threatened with extinction globally Explain which types of threats are have the largest impact on biodiversity List areas of the world that have high levels of biodiversity and many threats to species Compare the amount of biodiversity in the United States to that of the rest of the world 10-3: List and describe the four types of efforts to save individual species Explain the advantages of protecting entire ecosystems rather than individual species Describe the main provisions of the Endangered Species Act Discuss ways in which efforts to protect endangered species can lead to controversy Describe three examples of world-wide efforts to prevent extinction
