Definition of Adaptation

1
Definition of Adaptation

• Characteristics that allow an animal to survive
  in its environment. These characteristics allow
  the animal to find food, protect themselves,
  communicate, and mate
• Can be physical or behavioral

2
Definition of Symbiosis

• When organisms share food and other resources.
• In Bird Beak Buffet lab, you were birds that were
  sharing food and resources.
• There are three types of symbiotic relationships
  mutualism, commensalism, parasitism.

Other Examples of Mutualism (/)These guys are
Pals or Buddies

• Orchids and Fungi
• Orchid benefits because the fungi grows on the
  root and helps bring in nutrients to plant
• Fungi benefits because it ingests food from the
  plant during photosynthesis
• Fruit and Birds
• Bird benefits because the fruit provides
  nutrition for the bird
• Fruit benefits because the birds fly around and
  expel waste which in turn disperses fruit seeds
  to new areas
• Protozoa and Termites
• Termites benefit because the protozoa help
  termite digest cellulose and other large
  molecules in wood.
• Protozoa benefit because they get food and
  shelter

Other Examples of Commensalism (/0) These guys
are Hitchhikers

• Cattle Egret (bird) Cattle
• Bird benefits because the cattle stir up insects
  while they graze
• Cattle does not benefit from birds being around
• Barnacles Scallops
• Barnacles benefit because they attach to scallop
  as a place to live
• Scallops dont care and are unaffected by the
  barnacles.
• Pseudoscorpions Beetles
• Fake scorpions (have pincers but no sting)
  benefit by hitchhiking under the wing covers of
  large beetles. This way they can disperse to
  large areas quickly and avoid predators
• Beetles dont seem to care that they have a
  hitchhiker

5
Other Examples of Parasitism (/-)These guys are
Pickpockets

• Fungus Trees
• Chicken of the woods fungus benefits because it
  breaks down the tree and gets it nutrients
• The tree is harmed because it decays, gets weak,
  and becomes vulnerable to wicked weather
• Fleas Cats
• Flea benefits because it feeds on blood of the
  cat
• Cat is harmed because they lose blood
• Ticks Deer
• The tick benefits because it feeds on blood
• Deer is harmed because they lose blood and
  sometimes the tick can be poisonous

Vocab we have covered so far

• Physical adaptation
• Behavioral adaptation
• Migration Hibernation
• Symbiosis- when two organisms have a relationship
• Mutualism- both organisms benefit
• Commensalism- one organism benefits, the other
  gets nothing
• Parasitism- one organism benefits, the other is
  harmed
• Endangered
• Extinction

Limiting Factors in an ecosystem

• a limiting factor is one that controls a process,
  such as organism growth or species population
  size or distribution. The availability of food,
  predation pressure, or availability of shelter
  are examples of factors that could be limiting
  for a species population in a specific area.
  Climate, space, food, water and predators are
  limiting factors.

• 2. Line up around the basketball court and put
  your envelope between your feet. This is your

Bears in the woods story!

• You are now all black bears. All bears are not
  alike, just as you and I are not exactly alike.
  Among you is a young male bear who has not yet
  found his own territory. Last week he met up
  with a larger male bear in the big bears
  territory, and before he could get away, he was
  hurt. He has a broken leg. Another bear is a
  young female who investigated a porcupine too
  closely and was blinded by the quills. The third
  special bear is a mother bear with two fairly
  small cubs. She must gather twice as much food
  as the other bears.

Bears in the woods

• 1. Add up the total number on your cards.
• 2. Record this next to your name on the
  envelope.
• 3. Stand if you got a total of at least 10
• 4. 80 YOU SURVIVED!
• 5. Bears need at least 80 in 10 days to survive.
• 6. Why did so many of you die? Was there enough
  food?

12
Bears in the Woods

• ORANGE- Nuts (acorns, pecans, walnuts, hickory)
• BLUE- Berries and fruits (blackberries,
  elderberries, raspberries, wild cherries)
• YELLOW- Insects (grub worms, larvae, ants,
  termites)
• RED- Meat (mice, rodents, peccaries, beaver,
  muskrats, young deer)
• GREEN- Plants (leaves, grasses, herbs)

13
Bears in Arizona

• Nuts 20 pounds (25)
• Berries fruit 20 pounds (25)
• Insects 12 pounds (15)
• Meat 8 pounds (10)
• Plants 20 pounds (25)
• Total 80 pounds (100)

14
The numbers represent the pounds of food you
collected

• BLIND
• How many pounds did you collect?
• Will you survive?
• BROKEN LEG
• How many pounds did you collect?
• Will you survive?
• MOTHER
• Did you get twice the amount needed to survive?
• What will happen to your cubs?
• Will you feed your cubs first or yourself? Why?
• What would happen to her if she fed the cubs?
• What if she ate first?
• If the cubs die, can she have more cubs in the
  future
