1)Woodland riverQ: What adaptations are necessary for an organism
to survive successfully in this environment?
Murky coloring to blend with water; camouflage
Minimal Sunlight ~ Canopy of trees & foliage
Survive in Water & on Land
Herbivore/Omnivore
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
• Ability to adjust to differing salt levels (Salinity)
• Temperature variations
• Burrowing to avoid low tide predators
• Rigid shell to protect from predators
3)Savannah Salt MarshQ: What adaptations are necessary for an
organism to survive successfully in this environment?
• 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”
4) MountainsQ:What adaptations are necessary for an
organism to survive successfully in this environment?
• 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
5)PrairieQ:What adaptations are necessary for an
organism to survive successfully in this environment?
• 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
6)DesertQ:What adaptations are necessary for an
organism to survive successfully in this environment?
• 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
• 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
• 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
• 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
• 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
• 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
• 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
1) Find two plant and two animal organisms2) Describe the physical characteristics of each
of the organisms (these are adaptations!)3) Sketch your organisms4) Describe the purpose of two of the
adaptations/physical characteristics of your organisms
