Questions and Answers

Why does the Atacama Desert have such low precipitation?

  • All of the above. (correct)
  • None of the above
  • What is the primary driver of upwelling currents along the coast of California?

  • The Coriolis effect pulls surface waters offshore, allowing deeper water to rise.
  • Prevailing winds blow parallel to the coastline, forcing surface water away from the coast.
  • The wind and the Coriolis effect combine to drive surface waters away from the coast, allowing deeper water to rise. (correct)
  • Deep ocean water rises to the surface naturally, driven by density differences.
  • None of the above.
  • Which of these factors contributes to the dry conditions on the eastern side of a mountain range?

  • Moist air is forced to rise over the mountains, releasing precipitation on the windward side. (correct)
  • Air descends on the leeward side, becoming warmer and drier, inhibiting cloud formation. (correct)
  • The windward side of the mountain receives more solar radiation, leading to higher evaporation rates on the leeward side.
  • Differences in air pressure between the windward and leeward sides of the mountain cause dry air to flow from the leeward side to the windward side.

    Study Notes

    Ecology Review

    • Ecology is the study of the interactions between an organism and its biological and physical environment.
    • A population consists of individuals of the same species living in a particular area.
    • A community is all populations of species living together in a particular area.
    • An ecosystem is one or more communities of living organisms interacting with their non-living physical and chemical environments.
    • A biome is a large-scale biological community shaped by the physical environment.
    • The biosphere is all the ecosystems on Earth.
    • Abiotic factors are non-living environmental factors.
    • Biotic factors are living environmental factors.
    • Ecology differs from Environmental Science in that ecology focuses on the interactions between an organism and its environment, whereas environmental science examines the impact of humans on the environment.

    Ribeira Parasite Life Cycle

    • The parasite undergoes asexual reproduction producing free-swimming cercariae
    • Cercariae infect tadpoles.
    • Cysts (metacercariae) form around developing limb buds.
    • Cysts interfere with normal limb development causing limb deformities.
    • Deformities make amphibians more vulnerable to predators.
    • Matures in predator's body.
    • Eggs are released into water and hatch.
    • Miracidia infect snails.

    Key Ecological Terms

    • Adaptation: a trait that increases an individual's survival and reproduction in a specific environment.
    • Natural Selection: the process by which the frequency of a gene in a population changes because some phenotypes increase survival and reproduction.
    • Producer: an autotroph that uses energy from an external source to produce its own food.
    • Consumer: a heterotroph that gets energy by eating other organisms or their remains.
    • Net primary production (NPP): the energy captured by producers minus the energy lost as heat during respiration.
    • Nutrient cycle: the movement of nutrients between producers, consumers, and the environment.

    Hypotheses, Controls, Replication, and Data Analysis

    • Hypotheses must be testable and falsifiable.
    • Controls are groups in an experiment that are not changed.
    • Replication involves producing a similar outcome many times and can reduce the chance that variables that the experimenter didn't control will affect the results.
    • Data Analysis is used to determine if results are significant.

    The Physical Environment

    • Weather is the current conditions, while climate is the long-term averages and variation of weather over decades.
    • The Coriolis effect is the deflection of winds due to the Earth's rotation.
    • Seasonal temperature differences are caused by the tilt of Earth's axis, while latitudinal differences are due to how the sun's rays strike the Earth's surface.
    • Albedo is the amount of solar radiation a surface reflects.
    • Upwelling is where deep ocean water rises to the surface.
    • Hadley Cells, Ferrell Cells, and Polar Cells cause differences in precipitation at different latitudes due to high and low pressure.

    Biomes

    • Tropical rainforests are characterized by high rainfall, high biomass, and high biodiversity.
    • Tropical seasonal forests and savannas have distinct wet and dry seasons.
    • Deserts are characterized by high temperatures and low precipitation.
    • Temperate grasslands have grasses as dominant vegetation and frequent fires.
    • Temperate shrublands and woodlands have drought-resistant shrubs and small trees.
    • Temperate deciduous forests have deciduous trees that lose their leaves in the winter.
    • Temperate evergreen forests have coniferous trees that retain their leaves year-round.
    • Boreal forests (taiga) have long, severe winters and coniferous trees.
    • Tundras are characterized by cold temperatures, low precipitation, and permafrost.

    Climate Diagrams

    • Climate diagrams show temperature and precipitation patterns for specific regions or biomes over a year.
    • The data is analyzed to understand the distribution of water, temperature, nutrients, and biodiversity.

    Water Balance Equation for Plants

    • The water balance equation for plants is how much water a plant gains and loses.
    • There are many terms to keep in mind (solar radiation, convection, conduction, transpiration).
    • The plant maintains these conditions so that physiological functions continue operating effectively.

    Adaptations to Environmental Variation

    • Adaptations are long-term, genetic responses to environmental stress that increase ecological success.
    • Acclimation are short-term adjustments to stress.
    • Organisms use a variety of strategies (e.g., semi-frozen states, producing isozymes).
    • The upper and lower critical temperatures define the range over which organisms can function.

    Osmolarity and Water Balance

    • Osmolarity describes the solute concentration of a solution.
    • Animals and plants use adaptations that maintain osmotic pressure to survive differing environmental conditions.

    Autotrophs, Heterotrophs, and Photosynthesis

    • Autotrophs produce their own food using energy from sunlight (photoautotrophs) or inorganic chemicals (chemoautotrophs).
    • Heterotrophs obtain energy by consuming other organisms.
    • Different photosynthetic pathways (C3, C4, CAM) have different tradeoffs regarding water use efficiency and energetic efficiency.
