  • 1. How do organisms fit their environments?
  • 2. What are 4 main environments (biomes) of the Earth? Desert— very dry, little Tundra—cold, snowy, few trees precipitation, often hot! Rain forest —very wet, Great plains —many types of lots of trees, animals grasses, windy, some rain
  • 3. Make some hypotheses! What are some  What are some adaptations you would adaptations you would need in a desert? need in the arctic? What are some  What are some adaptations you would adaptations you would need in a jungle? need in a great plain?
  • 4. What is an adaptation?Adaptation - any structure or behavior that increasesan organism’s chance of survival in an certainenvironment  Avoid predators  Get more food/save energy  Make more babies/attract mates There are three types: 1. Structural: related to its physical form 2. Behavioral: related to what an organism does 3. Functional: related to the way it does a task Organisms have different adaptations becausethey live in different environments!
  • 5. Adaptations of Organisms in the Desert PLANT ADAPTATIONS ANIMAL ADAPTATIONS Structural:  Structural:  Shallow roots to soak up  large ears to give off heat water over a large area  Functional:  Deep roots to get to water  little urine to save water stored underground  Behavioral:  No leaves to reduce water loss  active only at night to avoid Functional: the sun and heat of the day  Photosynthesis in stems because no leaves  Flowers open at night when cooler
  • 6. Adaptations of Organisms in the Tundra PLANT ADAPTATIONS ANIMAL ADAPTATIONS  Structural: Functional:  Layer of fat— blubber  Small shrubs and mosses that  Two layers of fur grow low to the ground to keep  Bigger body from freezing  Behavioral:  Grow in clumps to protect one  Migration to warmer areas another from the wind and cold in the winter Structural:  Hibernations—deep sleep  Dark in color to absorb solar heat to save energy  Shallow roots to not have to penetrate ice
  • 7. Adaptations of Organisms in the Rain Forest PLANT ADAPTATIONS ANIMAL ADAPTATIONS Structural  Structural  Shallow roots because of  Camouflage in thick greenery shallow & moist soil or shadows  Waxy coating to protect leaves  Webbed limbs to glide across from fungus and bacteria that trees thrive in wet areas  Behavioral  Broad leaves to absorb the  Climbing and living in trees little sun that gets through the  Nocturnal lifestyle to avoid heat canopy of trees
  • 8. Adaptations of Organisms in the Great Plains PLANT ADAPTATIONS ANIMAL ADAPTATIONS  Structural  Structural  Soft stems allow prairie grasses  Limbs to move very quickly across to bend in the wind open spaces  Thick tree bark to resist fire  Behavioral  Grazing animals that eat grasses  Extensive root systems prevent grazing animals from pulling  Burrowing in the ground to avoid roots out of the ground or fires wind from destroying  Functional  Hunting in groups to catch prey  Functional  Prairie grasses have narrow leaves which lose less water  Wind pollinated seeds GO BUFFS!
