Ecology Review Which of the following is NOT a renewable form of energy? A) Water B) Solar C) Wind D) Coal E) Geothermal D A) Where does the energy come from and what is it converted to by this array? B) For an average American home, what percentage of electrical needs can be met by this solar array? 10%, 70%, or 100% A) Sun… electricity B) 70% • a. b. c. d. e. f. Which of the following is NOT true regarding the ozone layer. There is a hole in it Ozone protects us from UV light rays which causes sunburns and skin cancer The hole has been caused by chlorofluorocarbons. The hole is caused by an excess of carbon dioxide. The hole has caused an increase in the amount of skin cancer The hole has caused a decrease in the population of phytoplankton. d • Put an A for abiotic or a B for biotic factors of a community 1. Plant 2. Soil 1. B 2. A • Put the following in the correct order from smallest to largest areas of ecology AND give an example of each Ecosystem, population, biosphere, community • Population – Black bear • Community – Black bear, Deer, Grouse, etc. • Ecosystem/biome – Deciduous Forest • Biosphere - Earth List the 7 terrestrial biomes Which has the greatest biological diversity? • • • • • • • Desert Savanna Tropical Rainforest Tiaga Deciduous forest Grasslands Tundra • What are organisms (plants and algae) called that can obtain energy from sunlight through photosynthesis. • What are organisms called that need to get their energy from other organisms. • Autotrophs or producers • Heterotrophs or consumers • List the 4 different types of consumers/heterotrophs • • • • Herbivores Omnivores Carnivores Decomposers • Match the following types of symbiosis ____ Both organisms benefit a) commensalism ____ One benefits and the other is not harmed or helped b) parasitism ____ One benefits and the other is harmed c) mutualism • C • A • B • Give an example of each of the following: 1. Keystone Species 2. Generalist 3. Specialist 4. Pioneer species 5. Climax species 6. Exotic-invasive species 1. 2. 3. 4. 5. 6. Keystone Species – Sea otter Generalist – Canadian Geese Specialist – Ruffed Grouse Pioneer species - lichen Climax species – Maple tree Exotic species - lamprey • Why does the amount of energy get smaller as you get to the top trophic level? • Each organisms uses energy for their life processes so the amount of energy available is smaller as you go up the food chain. • If you didn’t mow your lawn explain what would happen in terms of succession. • Why do some areas naturally remain grasslands? • If you were to stop mowing you lawn after the grasses you would start seeing shrubs, and then small softwood trees and over several years (possibly even 100s of years) you would have hardwood trees or a climax forest. • wildfires • Which species is an autotroph/producer? • Name one herbivore and one carnivore. • What would be the final part of this food web? (it is not shown above) • • • • Plants Herbivore: rabbit Carnivore: fox Final part of food web: Decomposer (bacteria, fungi and/or earthworms) Populations that contain only a few individuals are a) Genetically more diverse than large populations. b) Able to withstand environmental disturbances c) Susceptible of extinction from habitat destruction, diseases and other environmental disturbances. d) Never bred in captivity because they fail to thrive when released into the wild. C Draw a diagram of the greenhouse effect. In your diagram show at least two greenhouse gasses. • Look at the following graph: http://www.esrl.noaa.gov/gmd/webdata/ccgg /trends/co2_data_mlo.pdf Why is there a rise and a fall in CO2 each year? CO2 levels have increased from 315ppm to close to 400ppm, why is this a concern? • During the winter most plants cannot photosynthesize and therefore do not absorb CO2 so the CO2 levels go up. Then in the summer when they can photosynthesize the CO2 levels go down. Although, the overall trend is an increase in CO2. • The additional CO2 is causing a warming of the Earth. • Regarding the carbon cycle what are the 3 main processes that put carbon dioxide into the atmosphere? • What is the one main process that takes carbon dioxide out of the atmosphere? • Cellular Respiration, Decomposition and Combustion • Photosynthesis • Regarding the nitrogen cycle what are the two ways nitrogen is put into the soil so plants can absorb it? • Nitrogen is necessary to make what kind of molecule? • How does the nitrogen get back into the atmosphere? • Why do farmers rotate their crops? • Nitrifying bacteria, legumes and/or lightning • Proteins (amino acids) • Denitrifying bacteria • They plant legumes like soybeans which put nitrogen in the soil and then they can plant corn which requires a lot of nitrogen. Global Warming is caused by an increase of greenhouse gases (mainly carbon dioxide) being put into the air from the burning of fossil fuels. This is causing an increase in hazardous storms, the rising of the sea level, increase in droughts, decrease in arctic habitat and an increase in infectious diseases. What can you do to help decrease the amount of carbon dioxide being put into the environment? Which of the following causes a decrease in biodiversity? A) Exotic-Invasive Species B) Overpopulation C) Over hunting/harvesting D) All of the above D Which of the following is not an exotic species in North Eastern Minnesota A) Round Goby B) Lake Trout C) Gypsy moth D) Ruffe B Which of the following is NOT true regarding acid rain? A) Acid rain has a pH of 2.5 – 4.5 B) Acid rain is caused by sulfur dioxide and nitrous oxide that is produced when fossil fuels are burned C) Acid rain causes more mercury to be released in aquatic environments D) Acid rain does not affect wildlife. D 1. Give an example of each of the following: A) Reduce B) Reuse C) Recycle 2. All 3 are important but which is going to have the best effect on the environment? 1. Reduce – buy less Reuse – use paper bags for storage or garbage Recycle – paper, aluminum, plastic 2. Reduce Which of the following is NOT true regarding wetlands. A) They provide habitat for many species B) All wetlands contain water year around C) Wetlands are “waste-land” D) Wetlands filter our water C What is bioaccumulation? When toxic chemicals become more concentrated as they move up the food chain. List 5 things you could do to lower your ecological footprint • • • • • Purchase less unneeded goods - Reduce Eat more locally grown foods Conserve Energy Recycle Reuse
