answer

epilimnion, thermocline, hypolimnion, benthos
question

biomes can be distinguished based on values from the two most important environment factors. which of the following abiotic conditions are the biggest determinants of biome location
answer

precipitation, temperature, light levels
question

Mediterranean shrublands (Chaparral) have been heavily impacted by humans because
answer

both they are near the oceans and have a moderate climate
question

which group of organisms forms the base of the energy pyramid in pelagic marine ecosystem
answer

phytoplankton
question

what is the dominant organism colonizing bare rock during primary succession
answer

lichens
question

epipelagic zone
answer

near the surface, this zone receives high levels of light and therefore is home to many photosynthetic organisms
question

littoral zone
answer

this zone occurs over the continental shelf, which is shallow enough for high levels of light. you can find many coral reefs in this zone
question

intertidal zone
answer

the daily fluctuations in water level for this zone require many of the organisms to be able to tolerate terrestrial conditions
question

hadal zone
answer

this is the lowest level in oceanic stratification. organisms found here have to be adapted to low temperatures, high pressure, and low light
question

in addition to northern latitudes, patches of tundra-like plant communities are also found
answer

on mountain tops
question

which is an example of secondary succession?
answer

a burned field
question

genetic diversity is influenced by which of the following ?
answer

migration, mutation, sexual reproduction
question

the taxonomic group that displays the greatest biodiversity is
answer

insects
question

invasive species
answer

do not release fish or vegetation from fish tanks into the wild
question

over-harvesting
answer

buy fish from stable populations such as farm-raised catfish and avoid slow growing top predators such as bluefin and albacore tuna
question

fragmentation
answer

buy shade-grown coffee, which is grown with other vegetation that provide habitats for different species of animals
question

an individual can help to control the spread of invasive species
answer

becoming informed of the issue, growing native plants, not releasing non-native plants, fisher other animals into water
question

the chief aim of CITES is to
answer

to prevent illegal international trade of endangered species
question

the number one cause of extinction is
answer

habitat fragmentation and loss
question

biodiversity is broad term used to describe the
