slide3

Murky coloring to blend with water; camouflage

Minimal Sunlight ~ Canopy of trees & foliage

Survive in Water & on Land

Herbivore/Omnivore

slide4
2)Haystack Rock, Oregon CoastQ: What adaptations are necessary for an organism to survive successfully in this environment?
able to survive for periods underwater and in air
Able to survive for periods underwater and in air
  • Ability to adjust to differing salt levels (Salinity)
  • Temperature variations
  • Burrowing to avoid low tide predators
  • Rigid shell to protect from predators
slide6
3)Savannah Salt MarshQ: What adaptations are necessary for an organism to survive successfully in this environment?
slide7

Inconsistent levels of saltiness in the water require organisms to adjust

  • Incoming and outgoing tide movement requires specialized roots for plants
  • Plants need mechanism for getting rid of salt (poisonous to plants)
  • Buffer the area provides between river and ocean allows organisms to use it as a “nursery”
slide8
4) MountainsQ:What adaptations are necessary for an organism to survive successfully in this environment?
slide9

Larger lungs to counteract low oxygen levels in the air

  • Large feet and tails for balance
  • Evergreen plants to take advantage of short growing season
  • Low growing plants for protection from winds and snow pack
slide10
5)PrairieQ:What adaptations are necessary for an organism to survive successfully in this environment?
slide11

Animals have broad, flat-topped teeth and digestive systems especially adapted to feed on grasses.

  • Short, powerful front legs and paws that allow for burrowing
  • Color blends with grasses
  • Some plants germinate only with fire, which is common on prairies
slide12
6)DesertQ:What adaptations are necessary for an organism to survive successfully in this environment?
slide13

Nocturnal to avoid desert heat

  • Plants and organisms store water
  • Large ears to dissipate heat
  • Plants slow growing in intense hot/dry seasons
ponds lakes streams
Ponds, lakes, streams
  • Fur that repels water
  • Large teeth to take down trees
  • Nose and eyes near top of head to allow easy view and breathing while swimming
  • Tail that works like an oar or paddle
ponds lake and estuary shorelines
Ponds, lake and estuary shorelines
  • Long legs for wading into water
  • Thin legs to move through water without creating a wake
  • Long beak and neck to quickly spear prey
  • Coloring blends with water
  • Large wings to enable gliding….less movement to distract prey
extreme cold heavy snow periods of little sunlight
Extreme cold, heavy snow, periods of little sunlight
  • Narrow tree downward angle of limbs shed snow w/o breaking branches
  • Evergreen to take advantage of times of low sunlight
  • Leaf shape and waxy coating to protect against dehydration
  • Heavy sap content to allow the tree flexibility in wind, cold and weight of snow
dry grasslands rocky areas
Dry grasslands, rocky areas
  • Scales to protect against dehydration
  • Coloring to blend with environment
  • Jaw which unhinges to swallow large prey
  • Pockets in jaw to “house” fangs
  • Venom to disable prey
  • Rattle to warn predators
rugged terrain
Rugged terrain
  • Hoofs flexible (like rubber) to climb rocks
  • Sturdy leg and hip joints to avoid injury from steep drops while descending
  • Fur for warmth
  • Eyes on either side of head for maximum peripheral vision to see predators
  • Horns for protection from predators
dark water
Dark water
  • No coloring because it lives in a dark environment (cave)
  • No eyes because it lives in a dark environment
  • Gills to absorb oxygen from the water
  • Fins to propel through water
  • Streamlined body shape to move efficiently through water
10 minute field trip
10 Minute Field Trip

1) Find two plant and two animal organisms

2) Describe the physical characteristics of each of the organisms (these are adaptations!)

3) Sketch your organisms

4) Describe the purpose of two of the adaptations/physical characteristics of your organisms
