BIO 182 EXAM 1- STHULTZ
QUESTIONS & ANSWERS 100%
CORRECT
ecology - ANSWERstudy of interactions among organisms and their enviroment
Biotic interactions - ANSWERInteractions among living things
Abiotic Interactions - ANSWERBetween organisms and the nonliving enviroment
Enviromental science - ANSWERApplication of ecology to real world problems
Physiological ecology - ANSWERInvestigates how organisms are physiologically
adapted to their enviroment
Behavioral ecology - ANSWERInvestigates how individual behavior contributes to
survival and reproductive success
Populations ecology - ANSWERFocus on groups of interbreeding individuals, called
populations
What is the goal of population ecololgy - ANSWERUnderstand factors affecting
populations growth, density and size
3 types of interactions between species - ANSWERPredation, competition, and
parasitism
Community ecology - ANSWERStudies how populations of species interact and form
functional communities
What does community ecology focus on - ANSWERWhy some areas are species
rich while others are species-poor
Clumped - ANSWERMost common
Resources tend to be clustered in nature
Social behavior may promote this pattern
Uniform - ANSWERCompetition may cause this pattern
May also result from social interactions
Random - ANSWERRarest
Resources are rarely randomly spaced
may occur where resources are common and abundant
, Succession - ANSWERHow species composition and community structure change
over time, particulary after disturbance
Ecosystems ecology - ANSWERStudies the flow of energy and cycling of chemical
elements among organisms within a community and between organisms and the
enviroment
What are levels in food chains called - ANSWERTrophic levels
Food chains interconnect and form what - ANSWERFood webs
An oranisms's habitat is what - ANSWERThe specific enviroment it lives in and
includes the biotic and abiotic factors of its surroundings
Biosphere - ANSWERThe global habitat or the sum of all the planet's life and where
it lives
The distribution of life on the planet varies on what - ANSWERGlobal and local scale
What are physical features of the enviroment - ANSWERTemp
Wind
Availability of water and light
Salinity
pH
Biome - ANSWERMajor aquatic or terrestrial life zone
What is a biome characterized by - ANSWERThe physical enviroment in aquatic
biomes or the vegetation type in terrestrial biomes
Aquatic biomes occupy what percent of earths surface - ANSWER75
What are aquatic biomes determined by - ANSWERSalinity and other physical
factors
Freshwater biomes - ANSWERHave a salt concentration of less than 1% and include
lakes, streams, rivers and wetlands
Marine biomes - ANSWERTypically have a salt concentration around 3% and
include oceans, intertidal zones, coral reefs and estuaries
What percent of earth do freshwater biomes cover - ANSWER1%
What are freshwater biomes used for - ANSWERDrinking water
Crop irrigation
Sanitation
Industry
What are the 2 broad groups that freshwater biomes fall into - ANSWERStanding
water which includes lakes and ponds and flowing water, such as rivers and streams
