recent? - Answers - byrophytes, ferns, gymnosperms, and angiosperms
the most successful animal group is the - Answers - arthropod group

the chordate group includes these animals - Answers - vertebrates
which is NOT true of yeast? - Answers - they are multicellular
Fungi are members of the domain - Answers - Eukarya
Fungi play a crucial ecological role in all terrestrial ecosystems, including those in
Olympic National Park. What is that role? - Answers - They are decomposers, breaking
down dead organisms and helping to recycle their nutrients
Major threats to biodiversity - Answers - Habitat loss, usually because of conversion of
natural habitat to human use
Fragmentation of remaining habitat by human-dominated landscapes such as highways,
urban areas
An expanding human population that consumes increasing amounts of resources
, An organism that is eukaryotic, multicellular, and has cell walls is - Answers - a plant or
a fungus
an organism that is eukaryotic, multicellular, and heterotrophic is - Answers - an animal
or fungus
an organism that is eukaryotic and photosynthetic is - Answers - a plant or a protist

the total number of wolves inhabiting Isle Royale is defined as a - Answers - population
a report based on the interactions of wolves, moose, ticks, and trees on Isle Royale
describes a(n) - Answers - ecosystem
a report that documents all the species (plant and animals) in an area but does not
include the environment describes - Answers - community
a researcher who investigates how flooding affects the different populations on an
island is most interested in which level of organization? - Answers - ecosystem
put the following in order from simplest to most complex - Answers - individual >
population > community > ecosystem
The ocean, sand, rocks, plants, seagulls, and invertebrates represent a(n) - Answers -
ecosystem
All of the polar bears, seals, fish species, whales, seabirds and the Aleut people in the
Aleutian Islands make up a(n) - Answers - community
Why do ecologists count representative samples of a population and not the total
population under study? - Answers - because it is impractical to count all the members
of the population
