E N D
Kingdom Animalia • Eukaryotic • No Cell walls • Multicellular • Heterotrophic • Sexual reproducers • Able to move (except sponges) • 95% are invertebrates (no backbone)
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 • 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 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 • 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?? • 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? • Lungs • Gills • Holes in exoskeleton • Holes in skin
How do animals obtain energy? • Cellular respiration • Glucose + Oxygen Carbon Dioxide + Water + ATP!! • Glucose is obtained through eating food
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? • Mitosis • Asexual body cells
How do animals regulate temperature? • Endothermic • Internal thermostat • Panting, licking, sweating • Exothermic • “cold blooded” • Depend on environment • Extra fat (ex: blubber) • Hair/Fur
