similarities
-protists share this feature with other eukaryotes - -they are photosynthetic

rivers in the tropics
-which trait do ferns, gymnosperms, and angiosperms share? - -vasculature
-which describes plant groups in order of terrestrial adaptations from earliest to the most
recent? - -byrophytes, ferns, gymnosperms, and angiosperms
-the most successful animal group is the - -arthropod group

-which is NOT true of yeast? - -they are multicellular
-Fungi are members of the domain - -Eukarya
-Fungi play a crucial ecological role in all terrestrial ecosystems, including those in
Olympic National Park. What is that role? - -They are decomposers, breaking down dead
organisms and helping to recycle their nutrients

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 heterotrophic is - -an animal or fungus
-an organism that is eukaryotic and photosynthetic is - -a plant or a protist
-an organism that is eukaryotic, heterotrophic, and lacks cell walls is - -an animal or a
protist
-the total number of wolves inhabiting Isle Royale is defined as a - -population
-a report based on the interactions of wolves, moose, ticks, and trees on Isle Royale
describes a(n) - -ecosystem
-a report that documents all the species (plant and animals) in an area but does not include
the environment describes - -community
-a researcher who investigates how flooding affects the different populations on an island
is most interested in which level of organization? - -ecosystem
-put the following in order from simplest to most complex - -individual > population >
community > ecosystem
-The ocean, sand, rocks, plants, seagulls, and invertebrates represent a(n) - -ecosystem

Aleutian Islands make up a(n) - -community
-Why do ecologists count representative samples of a population and not the total
population under study? - -because it is impractical to count all the members of the
population

-when a population reaches its carrying capacity, its growth rate will - -slow and remain
near zero
