Ecology

The scientific method deals with absolute truths: False The dispersal of the quanacaste tree’s seeds was performed by herbivores that have since become extinct; consequently, the tree is not on the verge of extinction: False Estuaries are junctions between rivers and lakes: False An ecosystem is defined as: all of the organisms that live in an area and the physical environment with which they interact Heating of the earth’s surfaces causes: warm air to rise and cool air to sink Robert MacArthur’s observations on the Warblers of North America indicate that they reduce competition by feeding in different zones. Most of the earth’s deserts are located at 30 degrees north and south latitudes. Tropical savannas and temperate grasslands are terrestrial biomes maintained by fires. Typically a shallow lake with large quantities of nutrients, high primary productivity, and large phytoplankton populations is deep green in color. Which of the following is not part of Darwin’s theory of natural selection? Fewer offspring are produced each generation than can be supported by the environment. Climatic diagrams provide all of the following information except wind patterns. Which of the following is the correct order of the major ocean basins from largest to smallest? Pacific, Atlantic, Indian All of the following statements are true concerning temperate lakes except: during fall and spring turnover, the oxygen rich hypoliminion moves up to the epilimnion. Aquatic organisms located off the ocean floor are pelagic. Evolution results from all of the above. (mutations, natural selection, genetic drift, gene flow) The timing and extent of tides are a function of all of the following except salinity levels. A biome is characterized primarily by climate and predominate plant types. Non-random mating is not a condition included in the Hardy-Weinberg equilibrium principle. Earth’s climatic variation is due to all of the above. Within a population, if the average is selected for and the...
