Ecol & Darwin Quiz Biology Jeopardy Review 100 Food webs & energy relationships Darwin Where does all the energy in a food web ultimately come from? Ecology is the study of relationships between what 2 factors? What is a producer? Organisms sharing the same space may have a ____ relationship? What is an omnivore? What term signals a relationship where both species benefit? The clown fish & sea anemone have what relationship? What term does Darwin use to describe changes in a species’ trait over time? Name at least 3 scientists who helped support Darwin’s theory? What does the saying survival of the fittest mean? Answer 1 of the following: About what year did Darwin make his travels? What was his ships’ name? On what islands did Darwin find his finches? Give at least 2 pieces of evidence that Darwin provided as fact of his theory? 200 300 400 500 What is the difference between a decomposer & a scavenger? What percent of energy is passed from 1 level to the next in a food chain or pyramid? Name a plant AND animal example involving a parasite relationship. Final jeopardy question: Miscellaneous Name 3 of the 5 limiting resources in a biome. What is nitrogen needed for in living things? Why is phosphorous important for living things? What does a K curve or carrying capacity on a population graph show? Name 3 concepts that determine the differences in biomes? describe the complete carbon cycle Answer sheet for Jeopardy Food webs & energy 100 the sun 200 A plant, algae or phytoplankton 300 400 An organism that eats both plants & animals Decomposers help break down nutrients for the soil, scavengers feed on dead organisms to obtain energy for themselves in the food web relationships *Biotic & abiotic *Living & non living *Organisms & their environments symbiotic Mutualism commensalism Answers may vary Ex. *Mistletoe & pine tree *flee/tick & dog Darwin Natural Selection Miscellaneous Food, water, shelter, space (niche or habitat) & carbon dioxide/oxygen Hutton, Mendel, Wallace, Lamarck, Malthus Nitrogen is part of amino acids & they build our proteins. Animals with adaptations or mutations in their genetics that benefit them to survive & reproduce in their environments are successful Phosphorous is part of the nucleic acid model (DNA & RNA)- life’s instructions 1831 The Beagle Galapagos Islands Fossil records, geographic locations, homologous structures, descent with modifications, embryo development, natural selection A plateau on the graph where it would tell that births equal deaths & the population has stabilized. This means that the environment is meeting all the needs of the organisms in that particular community. *Climate (weather, precipitation or temperatures) 10% *Latitude &/or altitude the globe *Typical plants & animals that live there *Major landforms like mountains, oceans, jet streams, etc Final jeopardy: Carbon dioxide gas is taken in by plants. Animals eat plants. Plants & animals die and decompose. Fossil fuels are burnt or organisms breathe, releasing carbon dioxide gas back into the atmosphere. 500 Score sheet 100 200 300 400 500 Food webs & energy relationships Darwin Miscellaneous
