Cards (27)

  • What does dentition refer to?
    The arrangement and type of teeth
  • What are the two types of representatives from the Hominidae family discussed?
    Omnivorous and herbivorous
  • What do herbivorous animals primarily eat?
    Plants
  • What type of teeth do herbivorous organisms have?
    Large flat teeth for grinding
  • What additional teeth do omnivorous animals possess?
    Sharp canine incisors
  • Why is understanding dentition important for studying extinct species?
    It reveals their dietary habits
  • What are the two general mouth adaptations in herbivorous insects?
    Jaw-like mouthparts and tube mouthparts
  • What do jaw-like mouthparts in insects help with?
    Biting and chewing
  • What do tube mouthparts in aphids allow them to do?
    Suck sap from plants
  • What adaptations do plants have to resist herbivory?
    Spines, toxins, and stinging parts
  • How do some herbivores overcome plant defenses?
    By producing saliva that blocks toxins
  • What adaptations do predators have for catching prey?
    Chemical, physical, and behavioral adaptations
  • How do prey avoid being eaten?
    Through chemical, physical, and behavioral adaptations
  • How do behavioral adaptations evolve compared to chemical adaptations?
    Behavioral adaptations evolve faster
  • What is the challenge for plants in the rainforest?
    Competition for light with other species
  • How do trees adapt to compete for light?
    By growing very tall
  • What adaptation do vines use to compete for light?
    They grow through other trees for support
  • What do epiphytes do to capture light?
    Grow on tree trunks where light is abundant
  • What do strangler figs do to their host trees?
    They outcompete and eventually kill them
  • How do shade-tolerant shrubs survive in low light?
    They have special adaptations for low light
  • What is an ecological niche?
    The role of an organism in its environment
  • What is the fundamental niche?
    All possible conditions for survival
  • What does the realized niche represent?
    The fundamental niche minus competition effects
  • How does competition affect an organism's realized niche?
    It reduces the size of the realized niche
  • What happens if a species is outcompeted in its entire fundamental niche?
    It gets excluded from the ecosystem
  • How does climate change affect species' niches?
    It can lead to exclusion from habitats
  • What is the impact of overlapping niches on competition?
    One species may outcompete the other
