Can I? List 3 types of adaptations? TOC # 20 Adaptation and Survival

An adaptation is a characteristic that improves an individual’s ability to survive and reproduce in a particular environment. Can I list 3 types of adaptations?

Three types of adaptations that help organisms survive are structural, behavioral, and physiological. Some examples of these adaptations are: Can I list 3 types of adaptations?

1. Obtaining Food Almost all organisms have adaptations to help them obtain food. Examples: Chameleon – long tongue Woodpecker – pointed beak Human – hands and fingers Can I list 3 types of adaptations?

2. Predator-Prey Many organisms have adaptations that serve as a defense against predators. Can I list 3 types of adaptations?

One common adaptation that helps predators and prey is called camouflage. An organism that is camouflaged is disguised so that it is hard to see even when the organism is in view. Animals that use camouflage are moths, spiders, alligators, etc. Can I list 3 types of adaptations?

Analyze this: With your elbow partner think of two animals that use camouflage to protect themselves from predators. Analyze how their camouflage protects them? Can I list 3 types of adaptations?

3. Interactions Two species can acquire adaptations because of their interaction with one another. Interactions take place between organisms that live close together. Can I list 3 types of adaptations?

4. Hibernation/Estivation A period of inactivity and decreased body temperature that some animals experience in the winter is hibernaton. Many desert squirrels and mice experience a similar internal slowdown in the hottest part of the summer which is called estivation. Can I list 3 types of adaptations?

5. Migration To migrate is to travel from one place to another. Animals migrate to find food, water, or safe nesting grounds. Organisms that migrate through TN are hummingbirds, butterflies, geese, cranes, etc. Can I list 3 types of adaptations?

Group Work- #3 person at each group will write the following on their desk with a dry erase marker: S P B Read each strip of paper and place it under S if it is a structural adaptation, P if it is a physiological adaptation, or B if it is a behavioral adaptation. Can I list 3 types of adaptations?

Natural selection The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do. There are four parts that make up natural selection. They include: Can I list 3 types of adaptations?

more offspring are born than will live to become adults. 1. Overproduction more offspring are born than will live to become adults. Can I list 3 types of adaptations?

2. Genetic Variation Individuals in a population differ from one another. Some characteristics improve chances while others lower chances for survival. Can I list 3 types of adaptations?

3. Struggle to Survive Many individuals die from lack of resources. Others are killed by predators or cannot find mates to reproduce. The ones who find resources, survive! Can I list 3 types of adaptations?

4. Successful Reproduction This is the key to natural selection. The strong survive, while the weak die early or have few strong offspring. Can I list 3 types of adaptations?

4 Phases of Natural Selection Can I list 3 types of adaptations? Pg. 87 4 Phases of Natural Selection Phase 1 Phase 2 Phase 3 Phase 4

Genetic Variation In natural selection, individuals within the population must be different. Over time, the population will be made up of more individuals with characteristics that help them survive. Can I list 3 types of adaptations?

If a population decreases rapidly, the characteristics of the individuals are reduced. This is called a genetic bottleneck. Can I list 3 types of adaptations?

What is happening in this diagram? What type of organism would make it to this side? Reason for population decline: Disease, Lack of food, lack of water, lack of adaptations, environment, habitat loss Humans are growing exponentially –J curve turns into S curve (carrying capacity) The struggle for survival in natural selection favors the survival of organisms that are well adapted to their environment. Can I list 3 types of adaptations?

Many characteristics may be lost entirely because the individuals with those characteristics died. As the population recovers, organisms are genetically similar causing genetic diseases to occur. Can I list 3 types of adaptations?

Exit ticket A. Green feathers and webbed feet The Arctic environment has temperatures that range between - 22° Celsius and 6°Celsius with snow covering some of the area. Which adaptation would most likely help a population of organisms survive this environment? A. Green feathers and webbed feet B. Large shell and leathery skin. C. Long necks and tall legs. D. Light colored fur and layers of blubber. Can I list 3 types of adaptations?
