Science Vocabulary and Notes-----Chapter 2 lesson 2----Adaptation and Survival Test Thursday, October 6, 2015 1. Adaptation- a characteristic that helps an organism survive in its environment. 2. Camouflage- an adaptation by which an animal protects itself against predators by blending in with the environment. 3. Mimicry- an adaptation in which an animal is protected against predators by its resemblance to another unpleasant animal. 4. Protective coloration- a type of camouflage In which the color of an animal helps it blend in with its background, protecting the animal against predators. 5. Protective resemblance – a type of camouflage in which the color, shape, and texture of an animal blends in with its background, protecting it against predators. Notes 1. Adaptations are important to organisms because successful adaptations help organisms survive in their environment. 2. Organisms inherit adaptations from their parent or parents when they reproduce. 3. There are two kinds of adaptations. a. Structural adaptations- are adjustments to internal or external physical structures that help an organism survive in certain environments. It deals with the organism’s structure. These 4. 5. 6. 7. 8. adaptations can also protect the organism or enable it to hunt more successfully. Examples: fur color, long limbs, strong jaws, web feet, scales, and the ability to run fast b. Behavioral adaptations- are adjustments in the organism’s behavior. An organism’s response to its environment. It is how the organism acts or behaves. Examples: woves traveling in a pack, migration, herd of animals, hibernation Migration- is a movement of animals to find food, reproduce in better conditions, or find a less severe climate. Examples of animals that migrate: birds, butterflies, fish, mantees Hibernation- is a period of inactivity during cold weather. Example of animals that hibernate: bats, snakes, frogs, bears Plant adaptations help plants get food and water and reproduce in their environment. Stomata are tiny pores on the leaves of plants where important gases enter and leave the plant. Some plant adaptations: a. Scented flowers to attract pollinators b. Leaves that catch sunlight c. Roots soak up water d. Pseudobulbs or “ false bulbs” which are storage organs(orchids) e. Thick, waxy stems to prevent water loss (cactus)
