ATTACHMENT PREVIEW Download attachment 3 pages unit 2 exam review.pdf Exam 2 Review BIO 130: Introduction to Environmental Science Chapter 7 Be able to list the seven major biomes, and compare them in terms of precipitation and temperature (precipitation is the primary factor that determines biomes, and temperature is the second most important factor), important plant life and animal species. Understand what is meant by the resilience of an ecosystem after a disturbance and the steps to ecological succession. Make sure you know what each of these trophic categories or food web terms are: Autotrophs, Heterotrophs (includes decomposers, consumers), Producers, Consumers (primary, secondary, tertiary). Where do herbivores, carnivores and omnivores fit into the consumer classes? Know the importance of the decomposers. Know how much energy is passed on from one trophic level to the next. What is the difference between a producer and a consumer? Be able to classify life as one or the other. Make sure you know the products and reactants for photosynthesis and cellular respiration. Understand bioaccumulation and be able to give an example. Understand the laws of thermodynamics and how they related to trophic levels and the cycling of matter. In each of the following cycles, be able to identify the primary source for each atom and how it is made accessible (atmosphere, lithosphere, and biosphere): Carbon cycle, Nitrogen cycle, Phosphorous cycle. Make sure you can list characteristics of a K-selected versus an r-selected. Is an elephant a K- or rselected organism? What about a fly? Understand habitat, niche and keystone predator. Know an example of a keystone predator. Know the difference between a condition and a resource. Know the difference between a generalist and specialist, which is prone to extinction and why. What is an adaptation? Be able to identify common types of adaptations of organisms (camouflage, spines on cactus, ability to store water in the desert, hibernation in cold climates, long necks to reach food, etc.). Understand coevolution and know some examples. Chapter 8 What are the classifications of life? Which group of organisms has the most discovered species? What is a biodiversity hotspot and where to they typically occur? Why is preserving biodiversity so important? What are the major threats to biodiversity? What are the effects of deforestation? Be able to define extinction, threatened and endangered. What is the rivet-popping hypothesis? Chapter 9 What equation is used to calculate natural population growth? Make sure you can calculate % natural population growth if given birth and death rates for a population. What is the shape of the human population growth curve going back to 0 A.D.? How is it expected to change in the future? What is a demographic transition? As countries become more industrialized (i.e. “developed” countries), what tends to happen to fertility/birth rates? Why? What was the global population at the end of 2013? What is it projected to be in 2025 and in 2050? Where is the most growth expected to take place? What 2 main factors account for population increases? Malthus predicted that human population will continue to grow until it is reduced by what 3 factors? What are the various population revolutions that have allowed population to grow, and approximately when did each take place? Even if you live in a developed nation, where population growth is small, why should you be concerned about the impact of human populations on the environment? Make sure you can define all of the variables in the IPAT equation, including the addition of the “S” variable. Why do people in developed nations tend to have higher “I” values as compared to citizens of developing nations? Chapter 10 Which is increasing at a faster rate – human population or food production? What are the competing interests for grains, besides feeding them to
