Plant and animal life faced challenges moving from water to land. Determine which statements about this transition are true and which are false. True False It was more difficult to reproduce on land. It was easier for animals to hunt on land. Radiation from the sun caused mutations. 2 Ecosystems provide many benefits to humans, which are termed "ecosystem services." Classify the following examples according to the type of ecosystem service each provides. Provisioning Regulating Cultural Supporting Soilformation Gardenvegetables TheGrandCanyon 3 Which statement below about Rachel Carson and her contributions to environmental awareness is true? She wrote an important book that closed the gap between biological and social sciences by examining the interactions between all living things. She published a book in 1962 about the effects of agricultural use of chemicals and pesticides on the environment and spurred a new national awareness of the environment. She wrote in 1949 that humans and nature depend on one another and humans are ethically obligated to protect the environment. She died in 1862, but she had great influence shaping the philosophy of modern-day environmentalism with early calls for protected wildlife areas. 4 Pair each group or organization with an example of how it might use environmental science. Scientists The public Non-profit organization A.Vote for a political candidate who supports environmental issues. B.Reintroduce an endangered species into a national park setting. C.Use data to formulate climate change predictions. D.Promote sanitation and clean drinking water in developing nations. 5 "DNA in mammal cells is arranged in distinct configurations within the mitochondrial system." Choose the most likely source for this quotation. The media, because it is a mixture of data, speculation, and scientific jargon A politician who wants to influence public opinion and further his own political agenda A scientist writing in non-scientific language to appeal more broadly to the general public A scientist writing in a scientific journal, because it uses language appropriate for its audience 6 Most scientists believe the event that led to the extinction of the dinosaurs was caused by a(n) __________. Asteroid impact Super nova Volcanic eruption Massive tidal wave 7 Match each scale of impact to an effect of overfishing of the world’s oceans. Individual Local Global A.A chain of restaurants in a coastal county begins to lose business B.A fish experiences hormone imbalances from pollution C.A fisherman loses his livelihood D.A fish species becomes extinct 8 Select the date and time of human arrival according to the one-year calendar model based on the Big Bang theory. December 30, 11:59 PM December 31, 11:54 PM December 15, 11:55 PM December 1, 12:00 AM 9 Choose the statement below that is NOT true about early Earth's atmosphere. Both ammonia and methane were present. The ozone layer was quite thick. Conditions were favorable for forming chemical bonds. There was no free oxygen. 10 Classify each statement as describing a physical law, a scientific theory, or a non-scientific theory. ScientificTheory PhysicalLaw Non-ScientificTheory Unchangingovertime Cannotbetested Can be supported but not proven 11 Evaluate the following activities as examples of environmental stewardship or environmental ethics. Stewardship Ethics A farmer does not allow hunting on his property. A homeowner captures rain in rain barrels. A new public library installs a green roof. 12 Choose the statement that is most likely made by an environmentalist rather than by an environmental scientist. “Human population growth is a current environmental issue, as is climate change.” "On average, 52 animal species move one step closer to extinction each year because of overpopulation and habitat destruction.” “Citizens must take matters into their own hands and start having fewer children to reduce the world’s population, starting now.” “When the number of existing humans exceeds the carrying capacity of the planet, we have reached the state of overpopulation.” 13 “All organisms share biological requirements for survival and well-being, and all should be respected equally.” The quotation represents a(n) __________ environmental ethical position. Ethnocentric Ecocentric Anthrocentric Biocentric 14 Evaluate whether each of the following is a sustainability issue as identified by the Brundtland report. Yes No Accesstofood Warmingoceans Humanlanduse 15 Categorize the elements as either biotic or abiotic. Abiotic Biotic Microorganisms Trees Air 16 Pair each graph image with its corresponding graph type and characteristics. A.Line graph in which data is depicted using horizontal or vertical bars B.Line graph in which data is depicted using a line connecting data points C.Scatterplot in which data is depicted using individual dots for data points D.Scatterplot in which data is depicted by using images to represent values 17 Which of the following is true about continental drift? Tectonic plates float on the molten core and are constantly in motion. The movement of tectonic plates is caused by earthquakes and volcanoes. Biodiversity is improved by the joining of continents, which decreases the amount of shoreline. Throughout the planet’s history, tectonic plates have remained in generally the same positions. 18 Read the statements describing environmental impacts of population growth. Choose the one that does NOT trace an accurate progression. More energy is needed, which leads to over-reliance on fresh water systems, which leads to water pollution. More land is required, which leads to deforestation, which leads to less oxygen in the atmosphere. More land is needed, which leads to habitat damage, which leads to loss of ecosystems. More energy is needed, which leads to burning of non-renewable natural resources, which leads to their depletion. 19 Of the four graphs below, select the one that is misleading. 20 Pair each term with its corresponding definition. Biodiversity Ecosystem Sustainability A.A community of living organisms interacting with its environment B.A movement that interacts with and protects the environment in a way that can continue indefinitely C.Humans protect the environment because of their ethical beliefs D.The variability of plant and animal life in a given area 21 Match the rate of growth to the projected population on Earth by 2050. Maintain exponential growth Continue current slowing growth Drastically slowing growth A.7.4 billion B.8.9 billion C.9.7 billion D.10 billion 22 Sherman notices the leaves of one tree in his yard begin to change color much earlier than the surrounding trees. He wonders what causes this. Sherman calls a local nursery to ask some questions. If Sherman follows the steps of the scientific method, his next action would be to __________. Form a hypothesis Analyze data Conduct an experiment Reach a conclusion 23 Jocelyn is making a chronological list of the events that occurred to create early life. 1. Inorganic molecules joined to form complex organic molecules. 2. Once encased in a membrane, these molecules began to replicate themselves. 3. __________. 4. One type of metabolism led to the production of oxygen. 5. Prokaryotes formed interdependent relationships to create eukaryotes. 6. Eukaryotes led to different cell types performing different tasks. Lightning in a water environment led to photosynthesis. Some prokaryotes joined together: one protected and one provided energy. Prokaryotes differentiated themselves into types, including bacteria. Called prokaryotes, the organisms developed the ability to metabolize. 24 Which statement about human population growth below is NOT true? From 200,000 BC through 8,000 BC, the global population was low. From 1350 AD to the present the world has experienced continuous population growth. Global population is expected to peak at 7 billion, then begin decreasing The world population doubled between 1959 and 1999. 25 Factors that led to population growth during the Industrial Revolution and the Green Revolution include all of the following except __________. improvements in technology government regulations increased food productivity improvedmethodsoftransportation
