BEHAVIORS FOR SURVIVAL

BEHAVIORS FOR SURVIVAL. BEHAVIOR AND STIMULUS. A behavior is an action performed in response to a stimulus. A stimulus is any other things that cause different behaviors. Ex. the feelings of hunger and thirst are internal stimuli.

  1. BEHAVIORS FOR SURVIVAL

  2. BEHAVIOR AND STIMULUS • Abehavior is an action performed in response to a stimulus. • A stimulus is any other things that cause different behaviors. • Ex. the feelings of hunger and thirst are internal stimuli. • External stimuli include factors such as air temperature, sunlight, or the appearance of a predator.

  3. GENETIC VS LEARNED BEHAVIOR • “Genetics and learned experiences play a role in shaping behavior”

  4. What are adaptations? Adaptations – an inherited characteristic that helps an organism to survive long enough to reproducemore successfully in its changing environment and can either be structural or behavioral.

  5. If red touches yellow, deadly fellow. If red touches black, friendly jack.

  6. A. Structural Adaptations Definition: Actual body parts or coloration that help an organism survive in their environment. EX: camouflage, mimicry, bent hind legs, sharp teeth and claws, body structures.

  7. B. Behavioral Adaptations • Definition: Ways an organism act to help them survive in their environment. • EX: Migration, hibernation, warning calls, mating dances, hunting in packs.

  8. Types of Structural Adaptations: 1. CAMOUFLAGE/COLORATION: blending in with the environment for protection from predators or to help sneak up on prey. Use: Obtaining food and protection

  9. Types of Structural Adaptations 2. MIMICRY: copying a behavior or appearance. Used for protection or obtaining food and protection.

  10. Types of Structural Adaptations 3. Bent hind legs – prey run fast to escape & predators run fast to catch prey Used for: protection, locomotion

  11. Types of Structural Adaptations

  12. Types of Structural Adaptations 5. Body Structures Predator – Eyes facing forward to find prey.

  13. BEAK DESIGN (Body Structure) • Birds' beaks are specially adapted so that they can eat different types of foods.

  14. We have been looking at structural adaptations of animals. ADAPTATIONS ON THE BODY, but animals can also have behavioral adaptations. This type of adaptation cannot be seen on the body. It is the way an animal reacts or behaves in certain situations. In other words: INSTINCTS

  15. B. Behavioral Adaptations • Migration - seasonal or periodic movement of animals in response to changes in climate or food availability, or to ensure reproduction. Examples: geese, whales, salmon, Monarch butterflies

  16. B.Behavioral Adaptations • Hibernation – adaptive winter survival • technique where animal becomes inactive • and all body processes slow down. Examples: bears, chipmunks, squirrels, bats,

  17. B. Behavioral Adaptations 3. Living in a Group – more eyes in a group to watch out for prey or predator, protection. Examples: fish, wildebeest, walruses, lions

  18. B. Behavioral Adaptations 4. Tool Use - any object manipulated by an animal in order to perform a specific task. (monkeys, otters, birds)

  19. B. Behavioral Adaptation • 5. Playing Dead - By pretending that they are dead, some animals escape bodily harm. (snakes, possums)

  20. B. Behavioral Adaptations 6. Calling – communication between animals 7. Threatening Gestures – scares off potential predators

  21. PLANT ADAPTATIONS Structural Plant Adaptations: 1. Structures - adaptations on the body: empty space for water storage, catch animals for minerals, tallness, heartiness, thorns, flexibility, floatation devices 2. Seeds – all seeds have adaptation to better enable it to survive long enough to plant itself and grow.

  22. Plant Adaptations 3.Protection – thorns, bad taste, poison, coloration, spikes 4.Obtaining Food – All plants do photosynthesis and make glucose in their leaves. The larger the leaves the more Sun they can capture.

  23. Plant Adaptations

  24. SEEDS Seeds are the baby plants!!! They are formed when the pollen fertilizes the egg. Fruit protects the seed.

  25. SEED ADAPTATIONS For plants to survive, seeds have to be dispersed away from the parent plant.

  26. Types of seed dispersal:

  27. PLANT BEHAVIORAL ADAPTATIONS A state of rest or inactivity. 1. DORMANCY - Many plants go dormant in the winter. Fall is the time of year when plants are preparing for dormancy. What other types of plants go dormant in the winter?
