Ecology part 2 1 What four areas does population size depend on? -# of Births -# of Deaths -Immigration (Entering Pop.) -Emigration (Leaving Pop.) 2 What shape is exponential growth and what causes it? • “J” • Unlimited resources (food, water & space) 3 Draw and describe exponential growth. • Slow initial growth that becomes rapid over time. 4 What is the shape and causes of logistic growth? •“s” •Exponential growth that slows or stops because of limited resources 5 Draw and describe logistic growth. • Exponential growth that slows or stops because of limited resources 6 What is the largest number of organisms of a species the environment can support? • Carrying Capacity 7 What types of factors are considered limiting factors that restrict population growth? • Biotic and abiotic that restricts population growth (ex. Food (biotic) & space (abiotic)) 8 What is density? • Amount of organisms in an area 9 What are the two types of limiting factors? • -Density-dependent • -Density- Independent 10 What are the three types of density dependent factors? • -Predation • -Disease • -Competition for resources 11 What are the three types of density-independent factors? • -Natural Disaster • -Weather / Climate • -Human Activity 12 In the water cycle, what two methods take water into the atmosphere and briefly describe each. • -Evaporation- From areas of concentration of water (Ponds, lakes etc.) • -Transpiration- H20 lost from plants 13 What is it called when water forms clouds? • Condensation 14 What is it called when water falls back to Earth and give 2 examples. • -Precipitation • -Rain • -Snow 15 What four methods release carbon dioxide/CO2 to the air? • • • • -Volcanoes -Human Activity -Respiration -Decomposition 16 What process uses carbon dioxide to make glucose? • Photosynthesis 17 Organisms use and release carbon dioxide by which process? • Respiration 18 What 2 important uses is carbon dioxide needed for to help humans? • -Food carbohydrates • -Living tissue and skeleton 19 What converts N2 in the soil for plants? • Bacteria 20 When organisms consume plants, what macromolecule does nitrogen help produce? • proteins 21 What three factors help return nitrogen to the soil? • -Dead organisms/ decompositions • -Bacterial nitrogen fixation • -Animal Waste 22 What breaks N2 down in the soil and returns it to the atmosphere? • Bacteria 23 Amino acids are monomers of which macromolecule that is vital to humans? • Proteins 24 How much of the atmosphere is nitrogen? • 78% 25 What saves/protects natural resources and organisms? • Conservation Biology 26. How many species are in danger of extinction in the U.S.? • 1,200 27 An organism that is likely to become endangered in the near future is considered? Give an example • -threatened Species • -Polar Bear 28 An organism that is subject to immediate extinction is considered? Give an example. • -Endangered Species • -Humpback Whale 29 What is a study over a long period considered? • Longitudal Analysis 30 What is an increase in the average temperature on Earth? • Global Warming 31 What is the trapping of heat in the atmosphere? What are 2 implications? • Greenhouse Effect- Deterioration of habit, drought and disruption of relationships 32. The water cycle: condensation, precipitation, runoff, transpiration, evaporation, seepage and root uptake. 33. Carbon cycle: co2 in atmosphere, co2 in ocean add photosynthesis. 34. What is moderate temperature areas called? • Temperate 35 What is called when a tree sheds its leaves every year during a particular season? • deciduous 36 List the biomes and their temperatures and seasons. • • • • • • • • • -Tropical Rainforest- Hot at top- Cool at Floor -Savanna- Hot -Desert- Hot day/Cold night -Temperate Grassland- Hot summers, cold winters -Temperate Deciduous Forest- Cold winters, moderate summers -Taiga- Bitterly cold winters, mild summers -Tundra- Very cold, with short cool summers -Lakes/Freshwater (Great Lakes)- Cold winters, warm/hot summers -Oceans (Cali. Coast) 50-70F 37 List the general locations of each biome. • • • • • • • -Tropical Rainforest – Along equator/oceans -Savanna- Eastern Africa -Desert- Near equator- not near ocean -Temperate Grassland- Midwest/central U.S -Temperate Deciduous Forest- Northern U.S -Taiga- Upper/Lower regions of earth (Not poles) -Lakes/Freshwater Great Lakes in Minnesota, Southern Canada • -Oceans (Cali. Coast) Duh, on the California Coast 38 List the wildlife for each biome. • Tropical Rainforest- Jaguars, Boa Constrictors, Monkeys etc • Savanna-rhinoceros, elephants and lions • Desert- rattlesnakes, golden eagle, and mountain lions • Temperate grassland- grizzly bear, coyotes and rabbits • Temperate deciduous forest- deer, bobcats, and squirrels • Taiga- moose, beavers, and Timberwolves • Great Lakes/freshwater- trout, bass and pike • Ocean/California Coast- seals dolphins and whales 39 List the plant life for each biome (if listed) • Tropical Rainforest- canopy-like trees, shorter trees and vines • Savanna- tall grass and fire resistant trees and shrubs • Desert- cacti and creosote bush • Temperate grassland- grass and herbs • Temperate deciduous forest-fern, moss and deciduous trees • Taiga- needle leaf /evergreen trees, berry bearing shrubs • Great Lakes/freshwater-lily pads and cattails • Ocean/California Coast- seaweed and kelp
