1. Adaptations & Natural Selection

2. NICHE
A habitat supplying factors necessary for existence of an organism and its ecological role in regard to food consumption.

3. Polar Bear Lives: Cold environment Why?
Blend in for hunting and protection
Job:
Keep population of seals down

4. Woodpecker Lives: Why? Job: In a tree Safe from predators
Control insect population that harms trees

5. ADAPTATION

17. Another Adaptation Asexual reproduction
A form of reproduction without a mother and a father; genetically identical to its parent (like a clone)
Strawberries plants will make runners, vines that will root and make a new plant
A potato will sprout and produce new potato plants

18. Fungi make spores that will explode off of themselves and make new fungi.
Black bread mold grows on bread
Black bread mold produces spores
Black bread mold spores spread over surface of bread and continue to grow more

19. Natural Selection
Process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the species
Therefore, they pass on the more desired traits for survival

20. Natural Selection
Its theorized that giraffes adapted to the climate change in Africa when it went from being a lush jungle to a drier savannah over two million years ago.
Normal food sources died out. Trees became the main food source, with leaves high up.
Offspring that were born with shorter necks could not reach the food and did not survive.
Only the giraffes with the longer necks were able to survive and reproduce, so the giraffe population passed on the long neck gene to its offspring.
