Mosses & Lichen are Examples What is a Pioneer Community? A measure of the amount of suspended particles in a body of water What is Turbidity? The rate at which light energy is converted to stored chemical energy of organic compounds by photosynthetic organisms What is Primary Productivity? The maximum population level an area can support What is carrying capacity? The fastest rate at which a population can grow What is biotic potential? Daily Double!! Percent Natural Rate of Annual Increase of a population with a BR of 18/1000/year and a DR of 9/1000/year What is 0.9%? All the members of a species that occupy the same area What is a population? The number of individuals in a given area What is population density? A viceroy butterfly and a monarch butterfly are examples of this type of mimicry What is Batesian mimicry? Type of Natural Selection Depicted Here: to Trait Trait What is Stabilizing Natural Selection? Rapid generation of new species from a single ancestor to fill new niches What is Adaptive Radiation? Type of Reproductive Isolation that occurs because of differences in the structure of the flower and the ability of pollination by insects What is Mechanical Isolation? Type of Evolution Depicted Here: QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. What is Convergent Evolution? Increasing concentration of a chemical up the food chain What is biomagnification or bioaccumulation? Caused by increased phosphorus, nitrogen, and potassium in a body of water What is Eutrophication? Caused by livestock overgrazing and the subsequent loss of topsoil What is desertification? Methane Carbon Dioxide Water Vapor & CFCs are all examples What are Greenhouse Gases? ____ + O2 CO2 + Water + Heat What is Natural Gas Combustion? A preservation strategy that adds individuals into an already existing population to increase genetic diversity What is augmentation? The nonrenewable energy source that is cleanest to burn What is natural gas? Director of the St. Louis Zoo, Started the Wolf Sanctuary, & Funded the Bird Sanctuary Who is Marlin Perkins?
