3.2 Adaptations

• Biodiversity refers to the variety of living organisms in a given area
• What is one example of an ecosystem service provided by biodiversity?

  Water purification
• Match the type of adaptation with its description:

  Structural ↔️ Physical features of an organism

  Physiological ↔️ Internal biological processes

  Behavioral ↔️ Actions or behaviors of an organism
• Biodiversity provides resources such as food and medicine
• Scientific importance of biodiversity includes research opportunities.


  True
• Adaptations increase an organism's chances of survival and reproduction.


  True
• Hollow bones in birds are an example of a structural adaptation for flight.

  True
• Give an example of a structural adaptation.

  Thick fur in polar bears
• Match the anatomical adaptation with its organism:

  Curved beaks ↔️ Hummingbirds

  Needles as leaves ↔️ Coniferous trees

  Hollow bones ↔️ Birds
• Photosynthesis in plants enables them to convert sunlight, water, and carbon dioxide into energy and nutrients.
• Prey animals like chameleons use camouflage to blend into their surroundings and avoid predators.
• Match the ecosystem service with its description:

  Nutrient cycling ↔️ Maintains soil fertility

  Water purification ↔️ Removes contaminants from water

  Climate regulation ↔️ Moderates temperature
• Biodiversity helps maintain healthy ecosystems and ecological balance.


  True
• Biodiversity refers to the variety of living organisms in a given area.


  True
• What is an example of a structural adaptation?

  Thick fur in polar bears
• Which type of adaptation involves the physical features of an organism?

  Structural
• Venom production in snakes is a physiological adaptation
• Match the behavioral adaptation with its example:

  Migration ↔️ Birds moving to warmer climates

  Hibernation ↔️ Bears conserving energy

  Camouflage ↔️ Arctic hares blending in

  Parental care ↔️ Elephants caring for offspring
• Biodiversity is important for maintaining healthy ecosystems.


  True
• Adaptations are traits that help organisms survive and reproduce.


  True
• Why is biodiversity ecologically important?

  Maintains healthy ecosystems
• What is the purpose of adaptations in living organisms?

  Survival and reproduction
• What is one example of a behavioral adaptation?

  Bird migration
• What are the three main categories of adaptations?

  Structural, physiological, behavioral
• Physiological adaptations involve internal biological processes like the venom production in snakes.
• Why do hummingbirds have curved beaks?

  To access nectar
• Hollow bones in birds are a physiological adaptation for flight.

  False
• Hibernation is a behavioral adaptation that helps bears survive during the winter months.

  False
• Parental care is a behavioral adaptation exhibited by animals like elephants and primates.


  True
• How do adaptations help maintain biodiversity?

  By allowing species to coexist
• What do adaptations help maintain in ecosystems?

  Biodiversity
• Match the importance of biodiversity with its description:

  Ecological ↔️ Maintains healthy ecosystems

  Economic ↔️ Provides valuable resources

  Scientific ↔️ Offers research opportunities
• Venom production in snakes is an example of a physiological adaptation
• Anatomical adaptations refer to the physical structures of organisms that help them survive.


  True
• What is an example of a physiological adaptation that allows bears to survive the winter?

  Hibernation
• Why is biodiversity crucial for the health and functioning of ecosystems?

  Supports ecosystem services
• Biodiversity helps maintain healthy ecosystems and ecosystem services
• Match the type of adaptation with its example:

  Structural ↔️ Thick fur in polar bears

  Physiological ↔️ Snakes producing venom

  Behavioral ↔️ Birds migrating to warmer climates
• Hummingbirds have curved beaks to access nectar from flowers
• Structural adaptations are the physical features that help an organism survive in its environment.
