Communities symbiosis

  1. 1.  Prepared by:  KRISTINE JOAN DA. BARREDO  Teacher II
  2. 2. STRATEGIC INTERVENTION MATERIALECOLOGICAL RELATIONSHIPS Learning Area Elementary Science Level Grade 6, Intermediate Learning Objectives Identify the kinds of relationship among living organisms Expected Outcomes * Classify the kind of relationship exists. * Identify the relationship among living things based on the given situation. Science Process Skills observing, communicating, inferring, identifying Keywords parasite, consumers, host. Predator, prey, mutualism, commensalism, predation, parasitism Author Kristine Joan DA. Barredo, Teacher II, Tunasan Elementary School Date June, 2011
  3. 3.  Symbiosis- A close relationship between two organisms where at least one organism benefits.  Types of symbiotic relationships ◦ Mutualism (both benefit) ◦ Commensalism (one benefits and one not affected ◦ Parasitism (one benefits and one is harmed) GUIDE CARD
  4. 4. Mutualism occurs when species interact in a mutually beneficial manner. The oxpecker gets food (ticks and insects disturbed in the grass) and a safe haven from the rhinoceros, and the rhinoceros has parasites (ticks) removed. GUIDE CARD
  5. 5. Example of mutualism: cleaner shrimp and a grouper fish Cleaner shrimp picks off parasites from the grouper’s mouth and gills. Both benefit. GUIDE CARD
  6. 6. Mutualism Mycorrhizal fungi (threads) covering aspen roots: fungi aid in water and nutrient absorption by the aspen and the aspen provides sugars and other food molecules to the fungi. GUIDE CARD
  7. 7. The remora attaches to a shark and rides to where the shark makes a kill. The remora eats the left over scraps of meat. GUIDE CARD
  8. 8. Commensalism: Barnacles and Grey Whales Barnacles attach to the head of the whale and feed on plankton where ever the whale swims. The barnacles don’t harm the whale. GUIDE CARD
  9. 9. Vampire bats feed on the blood of mammals without killing their host. GUIDE CARD
  10. 10.  Parasites feed off other organisms called “hosts”.  Parasites usually don’t kill their host. GUIDE CARD
  11. 11.  Ectoparasites- Live outside the host ◦ Example: ticks and humans GUIDE CARD
  12. 12. Head louse Mite bedbug GUIDE CARD
  13. 13.  Live within the host ◦ Example: guinea worms GUIDE CARD
  14. 14. Tapeworm Hookworm Roundworm GUIDE CARD
  15. 15. •ecological relationships in which one organism (population, species) benefits and the other is harmed GUIDE CARD A predator is an animal that hunts other animals for food. The animals that are eaten are the prey.
  16. 16.  Classify the following pictures as to what type of interrelationship exist among living things. ◦Write PREDATION, MUTUALISM, COMMENSALISM, or PARASITISM In your worksheet. ACTIVITY CARD #1

  21. 21. _____1. Eagles build their nests on treetops. The eagle are protected by the thick foliage. The trees are not harmed or benefited by the eagles. _____2. Many other birds find food and shelter in the trees in the forests. The birds help disperse the seeds of the seeds. _____3. Monkeys climb or swing among the branches of trees. The trees provide shelter to the monkeys. Hunters have a difficult time catching them. _____4. Bacteria and fungi feed on dead plants and animals. They break the dead organisms into simple nutrients the plants can use. _____5. Cats are hunting mice in the corners of the house. ACTIVITY CARD #2
  22. 22. Analyze the following pictures. Identify what ecological relationship exists in the living organisms. ASSESSMENT CARD #1
  23. 23. Mutualism ASSESSMENT CARD
  24. 24. Predation ASSESSMENT CARD
  25. 25. Commensalism ASSESSMENT CARD
  26. 26. parasitism ASSESSMENT CARD
  27. 27. Mutualism ASSESSMENT CARD
  28. 28. Choose the letter of the correct answer Read the questions carefully then choose the best answer on the choices given below.
  29. 29. a. commensalism b. mutualism c. parasitism d. predation ASSESSMENT CARD
  30. 30. a. Aphids produce honeydew needed by ants. In return, ants protect aphids from other insects. b. The ants eat the aphids. c. The aphids produces honeydew but the ants do not give any help nor harm the aphids. d. The aphids live on the ants habitat. ASSESSMENT CARD
  31. 31. a. Mutualism mean that both members of a species benefit from living together. Parasitism means that one member of a species benefits without harming or benefiting the member of another species. b. Mutualism means that one member of a species benefits without harming or benefiting the member of another species. Parasitism means that both species' members benefit from the relationship. c. Mutualism means that one member of a species thrives at the expense of the member of the species. Parasitism means that one member of a species thrives at the expense of the member of the species. d. Mutualism means both members of a species benefit from living together. Parasitism means that one member of a species thrives at the expense of the member of the species. ASSESSMENT CARD

  35. 35. We Are Not Immune! When it rains, most of the chemicals sprayed onto crops get washed into rivers, and eventually the sea. Click to move on Once a poisonous chemical is in the food chain, there is a good chance that humans will be affected. ENRICHMENT CARD
  36. 36.  As a student, how will you decrease the harmful contaminants in the environment? X ENRICHMENT CARD
