BSC 196 Exam 4 Questions With Correct
Answers


What are the different levels of biological organization at which
| | | | | | | | | |



biologists study ecological processes? - CORRECT ANSWER✔✔-
| | | | | |



Organismal ecology |




Population ecology |




Community ecology |




Ecosystem ecology |




Landscape ecology |




Global ecology |




Organismal Ecology - CORRECT ANSWER✔✔-Studies how an organism
| | | | | | | |



physiology, morphology, and behavior meet environmental challenges.
| | | | | |




Questions focused on specific adaptions: How does a shark locate its
| | | | | | | | | | |



prey?


Population ecology? - CORRECT ANSWER✔✔-A group of individuals of
| | | | | | | | |



the same species living in an area. Focuses on factors affecting
| | | | | | | | | | |



population size over time. How does clutch size influence the population
| | | | | | | | | |



size of flamingos?
| | |

,Community ecology? - CORRECT ANSWER✔✔-A community is a group
| | | | | | | | |



of populations of different species in an area. Examines interactions bw
| | | | | | | | | | |



species that influence community organization. How does competition
| | | | | | | |



influence diversity of plants in a tropical forest
| | | | | | |




Ecosystem ecology - CORRECT ANSWER✔✔-An ecosystem is the
| | | | | | | |



community of organisms in an area and the physical factors with which
| | | | | | | | | | | |



they interact. Emphasized energy flow and chemical cycling. What
| | | | | | | | |



factors influence photosynthesis in a grassland ecosystem
| | | | | |




Landscape ecology - CORRECT ANSWER✔✔-Landscape is a mosaic of
| | | | | | | | |



connected ecosystems. Focuses on the exchange of energy, resources,
| | | | | | | | |



and organisms across multiple ecosystems
| | | |




Do trees lining a river serve as a corridor for dispersal for animals?
| | | | | | | | | | | |




Global ecology - CORRECT ANSWER✔✔-Examines how energy effects
| | | | | | | |



organisms across the planet. How does ocean circulation influence
| | | | | | | | |



distribution of crustaceans. | |




How does solar energy influence global temperature, precipitation, and
| | | | | | | | |



wind patterns? - CORRECT ANSWER✔✔-solar energy near the equator
| | | | | | | | |



initiates global pattern of air circulation and precipitation
| | | | | | |




The global climate - CORRECT ANSWER✔✔-Patterns are determined
| | | | | | | |



largely by solar energy and Earth's movement in space. Angle at which
| | | | | | | | | | | |

, the sunlight hits earth affects the amount of heat and light at different
| | | | | | | | | | | | |



latitude
Drive evaporation and the circulation of air and water
| | | | | | | |




Cause latitudinal variation in climate
| | | |




Global precipitation - CORRECT ANSWER✔✔-Water evaporates in the
| | | | | | | |



tropics and warm, wet, air masses flow from the tropics toward the
| | | | | | | | | | | |



poles
Rising air masses release water and cause high precipitation especially
| | | | | | | | | |



in the tropics. (monsoons)
| | |




Dry descending air masses create arid climates especially near 30 north
| | | | | | | | | | |



and south |




Global air circulation - CORRECT ANSWER✔✔-As each rotates land near
| | | | | | | | | |



equator moves faster than land at poles
| | | | | |




Cooling trade winds blow from east to west in the tropics. Westerlies
| | | | | | | | | | | |



blow from the west to east in the temperate zones
| | | | | | | | |




How do the tilt of the earth and the movement of the earth around the
| | | | | | | | | | | | | | |



sun determine seasonal variation in light and temperature across
| | | | | | | | |



different latitudes? - CORRECT ANSWER✔✔-Seasonal variation in light
| | | | | | | |



and temperature increase steadily toward the poles. (more variable in
| | | | | | | | | |



temperate zones and poles) | | |
