    light pentetration
    salinity of water
    presence of predators
  • Q5

    ability to lose leaves during wettest part of the year
    plants with an inverted stomatal rhythm (open at night, close in the day)
    a thin waxy cuticle

  • Q7

    single-cells versus multicellular
    presence of membrane bound organelles
  • Q9

    have the same number of chromosomes
    are not members of the same species
    are members of the same species
    are not closely related

  • Q11
    In food chains and food webs, the arrows are best described as representing
    flow of energy from high trophic level to lower tropic levels
    movement of matter from consumers to producers and decomposers
    the movement of matter and energy from one trophic level to the next highest level
    the flow of energy from primary consumers to secondary consumers
  • Q12
    Light energy is the energy source for most ecosystems. Light energy is used by autotrophs to produce organic material. The energy has been converted to chemical energy that can be stored. When compounds are broken down some energy is unavoidably lost as
    chemical energy
    kinetic energy
    light energy
    heat energy
  • Q13
    Parasite/host relationships are often very complex. Parasites have special adaptations to allow them to obtain nourishment from the host. With regard to these relationships the most accurate statement below is
    exoparasites live inside their host
    endoparasites live inside their host
    parasites eventually kill their host
    the host gains benefit from the parasites activities
  • Q14
    Relationships between organisms in a community can be classified on the benefit or harm to those involved. Organisms where neither side is harmed include
    parasite/host relationship
    predator/prey relationships
    intra-specific competition
  • Q15
    With respect to competition between organisms, the following statement is true,
    intra-specific competition is more intense than inter-specific competition
