continuity of organism life

  1. 1. CONTINUITY OF AN ORGANISM LIFE Chapter III Ms. Ruth
  2. 2. Organism on the earth are predicted to have been existed for million years. The fact show that there is continuity of life of organism. How do organisms sustain their continuity of life? The continuity of an organism life occurs through internal factors include adaptation and reproduction while external factor is natural selection.
  3. 3.  The environment surrounding organism always changes, such as temperature, sunlight, water and food. These changes will influence the continuity of an organism’s life. How can such organism survive?  An organism that is able to survive is an organism which is adaptable. Adaptation is the ability of living organism to adjust itself to its environment and then inherit that ability to its descendants.  Adaptation is a characteristic development of an organism which make it more suited to live and reproduce in an environment.
  4. 4.   Living organism have different adaptive ability, some adapt easily while others difficult to adjust.  Living organism that have high adaptive ability will easily adjust to its environment. The organism with low adaptive ability will have a hard time adjusting to its environment and may not survive or even extinct.  There are 3 adaptation processes which are performed by organism to survive in order to preserve their species, they are : morphological adaptation, physiological adaptation, and behavioral adaptation.
  5. 5.   Morphological Adaptation is an adaptation of the shape of body parts or body organs of organisms to their environment .  For example : shapes of birds beak, shapes of birds foot, types of insects mouth, and streamline fish shapes. Morphological Adaptation
  6. 6. * The shapes of bird’s beak is adjusted according to the kinds of food they eat.
  7. 7. *
  8. 8. *
  9. 9. Biting or chewing type Insects which bite, have strong upper and lower jaw, for examples : grasshopper and cockroach, cricket.
  10. 10. Sucking or siphoning type These insects have a long extracting organ that can be curled, for example : butterfly. Butterflies use this mouth part to extract nectar from the flowers, true bug use it to extract fluids from plants and animals.
  11. 11. Licking or sponging type These insects have organs to lick or called the lips, for examples : bees and flies.
  12. 12. Piercing and sucking type These insects have strong, long, and sharp jaws, for examples : mites and mosquito.
  13. 13. * Fish with streamlined bodies usually fast swimming that may swim in high speeds most of the time. They can move into one to another areas to hide, to escape from predators or to get food that cannot be reached by other fish. * Even tough a penguin, an octopus, and a squid do not have a body shape like fish, they can change their body into a streamlined shape when they swim quickly in the water.

  17. 17.   Physiological Adaptation is an adaptation of organs functions and system toward an environment. Changes that occurs during adaptation is not physically visible. Physiological Adaptation
  18. 18.   Behavioral Adaptation is self adjustment to the environment by changing its behavior. Behavioral Adaptation
  19. 19. Factors affecting organism adaptation
  20. 20. Reproduction Generative / sexual Reproduction Pollination Fertilization Vegetative / asexual Reproduction Natural vegetative propagation Bulb, rhizome, stem tuber, root tuber, stolon, shoots, adventitious shoots. Artificial vegetative propagation Air layering, ground layering, cutting.
