ADAPTATIONS & NATURAL SELECTION

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

POLAR BEAR • Lives: • Cold environment • Why? • Blend in for hunting and protection • Job: • Keep population of seals down

WOODPECKER • Lives: • In a tree • Why? • Safe from predators • Job: • Control insect population that harms trees

ADAPTATION • A characteristic that helps an organism survive and reproduce. • Survive means: eat, blend, hunt, protect self, find food, etc.

DESERT FOX • Hot environment • Big ears

ARCTIC FOX • Cold environment • Small ears

DESERT RABBIT • Hot environment • Big ears

ARCTIC HARE • Cold environment • Small ears

BIG IDEA Heat escapes through the ears

ADAPTATIONS • Bioluminescence • Light that is given off by a creature • Lightening bugs • Angler fish • Mushrooms in Brazil

ADAPTATIONS • Echolocation • An animal’s (or human’s) ability to tell where an object is by detecting the sound bouncing off of it • Bat, dolphins

ADAPTATIONS • Flippers • Legs that are specialized for swimming • Sea turtles • Ducks • Walrus

ADAPTATIONS • Claws • Used for gripping, digging and tearing things apart • Bears • Moles • Cats

ADAPTATIONS • Smell • Ability to detect scent to find food, a mate, or avoid danger • Vultures • Turkey • Dogs

ADAPTATIONS • Teeth • Used for tearing, chewing, ripping food for consumption • Sharp • • Lion • Eating Meat Flat • Horse • Grass/Grains Baleen (filter-like) • Blue Whale • Krill Mixed • Humans • Meat and plants

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

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

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

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.

• Genetic Diversity- VOCABULARY • Difference in the genes among a species • If every human was exactly the same and an infectious, deadly disease came around, what would happen? ? ? • Variations • Any difference between individuals of the same species • Resilient • Able to overcome a tough situation • Continuous • Never ending; cycle • Water cycle, carbon cycle, changes • Migration • Movement of a species during certain times of the year • Birds, sea turtles, monarchs • Competition • Interaction among organisms by which they compete for survival, for biotic and abiotic factors, reproduction, and hierarchal position.
