Bio 202 Exam 1 Questions & Answers 100% Correct
Global ecology - ANSWER-examines how the regional exchange of energy and materials influence the functioning and distribution of organisms across the biosphere.
Landscape ecology - ANSWER-focuses on the factors controlling exchanges of energy, materials, and organisms across multiple ecosystems.
Ecosystem ecology - ANSWER-emphasizes energy flow and chemical cycling between organisms and the environment.
Community ecology - ANSWER-examines how interactions between species, such as predation and competition, affect community structure and organization.
Population ecology - ANSWER-analyzes factors that affect population size and how and
why it changes through time.
Organismal ecology - ANSWER-includes the subdiscipline of physiological, evolutionary,and behavioral ecology, is concerned with how an organism's structure, physiology, and behavior mee the challenges posed by its environment.
Latitudinal variation in sunlight intensity - ANSWER-Earth's curved shape causes latitude variation in the intensity of sunlight. Because sunlight strikes the tropics ( those regions that lie between 23.5 N and 23.5 S) most directly, more heat and light per unit of
surface area are delivered there. At higher latitudes, sunlight strikes Earth at an oblique angle, and thus the light energy is more diffused on the Earth's surface.
Global air circulations and precipitation patterns - ANSWER-Intense solar radiation near
the equator initiates a global pattern of air circulation and precipitation. High temperatures in the tropics evaporate water from earth's surface and cause warm, wet air masses to rise and flow towards the poles. As the rising air masses cool, they release much of their water content, creating abundant precipitation in tropic regions.
Hadley cells - ANSWER-The high altitude air masses, now dry, descend towards earth around 30 N and S, absorbing moisture from the land and creating an arid climate conducive to the development of the deserts that are common at those latitudes.
Air flow on the Earth's surface - ANSWER-creates predictable global wind patterns. As Earth rotates on its axis, land near the equator moves faster than that at the poles, deflecting the winds from the vertical paths and creating the more easterly and westerly flows .
Circulation of surface water in the oceans around North America - ANSWER-The California current carries cold water southward along the western coast of North America. Along the eastern coast, the warm water of the Gulf stream flows northward to
northern Europe.
Coastal mountains create rain shadows - ANSWER-Cool air flows inland from the water
moderating temperatures near the shore. Air that encounters mountains flows upward, cools at higher altitudes, and releases water as rain and snow. Less moisture is left in the air reaching the leeward side, which therefore has little precipitation. This rain shadow can create a desert on the back side of the mountain range.
Macroclimate - ANSWER-climate of a large geographical area (temperature and rainfall)
Microclimate - ANSWER-climate actually experienced by an individual
Biomes - ANSWER-are major life zones. Characterized by vegetation type (terrestrial biomes) or physical environment (aquatic biomes). Climate (temperature and rainfall) usually determines the biome. Disturbance can also play an important role (storm, fire, or human activity)
Tropical forest - ANSWER-High temp, high competition, many species
Equatorial and sub equatorial regions. Temperature is usually high. Little seasonal variation.
Tropical rain forests have constant rainfall 200-400cm annually.
Tropical dry forest precipitation averages about 150-200cm annually with 6/7 month dry season.
Forests are vertically layered, and plants compete strongly for light. Has the highest animal diversity than any other terrestrial biome. Broadleaf evergreens are dominant
Savanna - ANSWER-Hot, seasonal rain, many grasses/forbs
Equatorial and sub equatorial regions.
Rain fall averages 30-50cm annually, dry seasons can last 9 months. Temperature is usually high, but varies seasonally more than the tropical forests.
Scattered trees have adapted to dry conditions. Fires are common in the dry season, and the dominant plant species are fire adapted and tolerant of seasonal drought.
Desert - ANSWER-Low precipitation, can be hot/cold
Occur in bands near 30 N and S latitude or at other latitudes in the interior continents( ex. Gobi desert).
Precipitation is low and highly variable, less than 30 cm/year.
Low vegetation that carries out C4 or CAM photosynthesis.
