Quiz help – Test One Chapters Biology is study of Life Definition Ecosystem: Community that is interacting with its physical environment. Biosphere: Regions of the earth’s waters, crust and atmosphere that hold organisms. Abiotic: Factors that are nonliving. Such as solar energy, water, temperature, wind, and disturbances. Biotic: factors that are living. Such as predation and competition. Can lead to the evolution of adaptations by natural selection. Effect on species number moving from equator: There are fewer species as you move farther from the equator. Eutrophic lake : Body of standing freshwater. Shallow, nutrient-rich; has high primary productivity . Oligotrophic lake : Deep, nutrient-poor; has low primary productivity. Seasonal Lake Overturn: In spring and fall , temperatures in the lake become more uniform. Oxygen-rich surface waters mix with deeper oxygen-poor layers. Nutrients that accumulated at bottom are brought to the surface. Atomosphere layers Outer Mesosphere: 50-90 km Middle Statosphere: Includes ozone layer, 10-50 km. Inner Troposphere: Where air is warmed by the greenhouse effect, 0-10 km. Gray smog: Industrial smog. Forms over cities that burn large amounts of coal and heavy fuel oils; mainly in developing countries. Main components are sulfur oxides and suspended particles. Brown Smog: Photochemical smog. Forms when sunlight interacts with components from automobile exhaust . Nitrogen oxides are the main culprits. Hot days contribute to formation. Population: a group of individuals of the same species occupying a given area. Community : all the populations that live together in a habitat. Distribution types and examples of animals Clumped: dispersion is when individuals aggregate in patches – fish, humans Uniform: dispersion is when individuals are evenly spaced - penguins Random : dispersion, the position of each individual is independent of the others - forests Examples and what the following mean Learning: responses change with experience. Birds learn the details of the song from others around it. Innate behavior : performed in same way by all individuals of a species. Bees, red belly fish. Imprinting: Time dependent form of learning. Triggered by exposure to a simple sign stimulus. Geese hatchlings treat the first moving object they see as their mother. Fixed action pattern : response is a stereotyped motor program. Like bees going to the circle that used to surround their nest or a fish attacking something with a red belly.

Associative learning : Animals may learn to associate a stimulus or behavior with a response. Trial and error learning: an animal learns that a particular stimulus or a particular response is linked to a reward or punishment. Sign stimulus:
