1. Warm-Up 3/1/17 and 3/2/17 Think of a Bumble Bee… What is its habitat?
What is its niche?
3) Identify the abiotic and biotic factors in the picture?
4) What is the organization of life? (Start with organism and get larger).
Loss of an organism

2. Predator and Prey

3. Adaptations
Every organism has a variety of adaptations (characteristics) that are suited to its specific conditions which help the organism to survive.
The adaptations can also assist them in their interactions with other organisms.

4. Predation
An interaction in which one organism hunts and kills another organism for food is called predation.
Definitions:
Predator
the hunter
Prey
the hunted

5. Predator Adaptations Helps them catch & kill their prey Speed
Stingers, toxins, sharp teeth
Camouflage (blending in)
Night vision

6. Prey Adaptations
Also known as “defense strategies” to avoid predation:
Camouflage
Protective coverings
Warning coloring
Defensive chemicals
Mimicry
False coloring

7. Camouflage
Prey blend in to their environment to avoid being eaten by predators.

8. Protective Coverings This might include needles, spikes, shell, etc.
Hedgehog

9. Warning Coloring
Bright colors warn predators that the prey may be poisonous and to stay away!

10. Defensive Chemicals
Some animals defend themselves with distinctive sprays/smells.

11. Mimicry
The ability some animals have to resemble another animal (usually a more harmful one) so closely that they can fool either their prey or their predators.
Coral Snake
King Snake
Ex: Coral Snake is venomous. King snake is not, but closely resembles Coral snake.
Ex: Monarch caterpillars eat milkweed. The white, milky substance in milkweed is toxic to many animals--but not to monarchs. This poison carries over to the adult butterflies, therefore predators avoid eating monarch butterflies because of this poison.
Viceroy butterflies do not have this poison but resemble Monarchs.
Monarch
Viceroy

12. False Coloring
Used to trick predators (spot can be mistaken for eyes, etc.)

13. Please remember…
Adaptations are traits with a current functional role in the life of an organism
This can go beyond predator/prey relationships
Mating/reproduction
Environmental Adaptations
Ex: For the proboscis monkey, the larger the male’s nose, the better chance he has for finding a female mate. The nose also helps make loud warning calls.
Ex: These Fennec foxes use their large, sensitive ears to let off heat, and to hear prey moving underground.

16. Owl Pellet Lab
Let’s dissect a real example of a predator-prey relationship…
Download the Owl Pellet Lab from my class website
You will complete the lab with your group
Step 1: Measure length, width and mass of owl pellet and take picture
Step 2: Write observations about the exterior
Step 3: Match bones on owl pellet bone chart and take picture
Step 4: Build prey-animal skeletons and take picture, label skeletons
Analysis Questions will be HW if not finished in class
*Submit to JG when completed*
