Animal Kingdom


Kingdom animalia

Kingdom Animalia

  • Eukaryotic

  • No Cell walls

  • Multicellular

  • Heterotrophic

  • Sexual reproducers

  • Able to move (except sponges)

  • 95% are invertebrates (no backbone)


Adaptations

Adaptations

  • Animals have specific adaptations to make them successful in their environment

Camel hump actually stores fat; can drink 53 gallons of water in 3 minutes; while exhaling, water vapor is trapped in nostrils and then reabsorbed; feces is really dry


Transport through animals

Transport through Animals

  • Large animals have a circulatory system with blood to transport nutrients and gases

    • Smaller animals (ex: worms) rely on osmosis and diffusion through skin


Excretion in animals

Excretion in Animals

  • Excretion involves the removal of wastes (main is ammonia)

  • Animals have complete digestive systems (mouth  anus)

  • Cellular waste products are also carried through the blood stream (ex: CO2)

  • Animals with kidneys filter out wastes


Nutrition in animals

Nutrition in Animals

  • Filter feeders – worms

  • Special mouthparts – insects

  • Specialized teeth – mammals

  • Beak adaptations – birds

  • Digestive system breaks down nutrients; diffusion occurs into cells


How do animals regulate water

How do animals regulate water??

  • Land and Freshwater Animals:

    • Water is re-absorbed in kidneys and intestines

      • Urine can be concentrated to conserve water

      • Feces is dry

      • “Thirst” is felt from low water content in blood

      • Water is pulled from cells (ex: mouth becomes dry)

  • Marine Animals:

    • Water is constantly taken in, salts are removed (ex: salt glands on tortoise)


How do animals exchange gases

How do animals exchange gases?

  • Lungs

  • Gills

  • Holes in exoskeleton

  • Holes in skin


How do animals obtain energy

How do animals obtain energy?

  • Cellular respiration

    • Glucose + Oxygen  Carbon Dioxide + Water + ATP!!

  • Glucose is obtained through eating food


How do animals reproduce

How do animals reproduce?

  • Sexually

    • Eggs + Sperm

    • Some reproduce externally by laying eggs and external fertilization

    • Some reproduce internally

      • Placental mammals

      • Marsupials

      • Lay eggs


How do animals grow

How do animals grow?

  • Mitosis

    • Asexual body cells


How do animals regulate temperature

How do animals regulate temperature?

  • Endothermic

    • Internal thermostat

    • Panting, licking, sweating

  • Exothermic

    • “cold blooded”

    • Depend on environment

  • Extra fat (ex: blubber)

  • Hair/Fur
