1
Adaptations and Extinction 01/10/13 page 83-84 Know: What qualities does a species need to promote survival?
2
Adaptations and Extinction Clarifying ?s Adaptations Information Physical/behavioral changes that are inherited enhances ability for species to survive/reproduce in a particular environment
3
Adaptations and Extinction Clarifying ?s Types of Adaptations that aid survival Information 1. Behavioral: actions Ex. Going into pool on hot day 2. Physical: body parts that control life processes Ex. Gills to breathe 3. Structural: Body part/coloring Ex. Feathers that blend into plant colors
4
Adaptations and Extinction Clarifying ?s Why adapt to environment? Information Species will not survive if it does not adapt. Ex. Cactus stores H20 in order to survive in desert, spikes prevent animals from taking H20 from plant.
5
Adaptations and Extinction Clarifying ?s How do humans adapt to their environment? Information Too warm– cool drink/treat, less clothing.. Too cold– more clothing, warm drinks, camp fire
6
Adaptations and Extinction Clarifying ?s Extinction Information Species no longer exists– happens to plants and animals Ex. Golden Frog. Dodo bird
7
Adaptations and Extinction Clarifying ?s How does extinction happen? How does environment change? Information Environment changes, species’ adaptive characteristics are Insufficient for it to survive. 1.Over hunting of species 2.Loss of habitat 3. Loss of food source 4.Natural disaster Ex. Flood, fire, volcanic eruption, tornado, hurricaine.
8
Evidence There is a 10 year drought in Washington State, predict which species has the greatest chance of survival and explain your reason– draw a picture to support your position Choose only ONE: 1. Spotted Owl 2. The Evergreen Tree 3. Cougar
