Interaction of Living Things

  1. 1. Interaction in the Ecosystem
  2. 2. Review: Classify the organisms according to the kingdom where they belong: Kingdom Plantae
  3. 3. Kingdom Monera
  4. 4. Kingdom Fungi
  5. 5. Kingdom Protista
  6. 6. Kingdom Animalia
  7. 7. Objectives: • Describe how living things interact with each other; • Make a chart that shows the relationship among living things; • Realize the importance of maintaining harmonious relationship with each other.
  8. 8. “And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in him.” 1 John 4:16
  9. 9. Having a good and harmonious relationship is important to maintain peace and order in the society.
  10. 10. Relationship among Living Things • Predation • Competition • Cooperation • Symbiosis a. Mutualism b. Parasitism c. Commensalism
  11. 11. Predation • A stronger organism called the predator eats the weaker organism called the prey. Predator Prey
  12. 12. Predator Prey
  13. 13. Competition • Some living things have the same need that is why they used to fight each other. Intraspecific Competition- involves organisms of the same kind/species.
  14. 14. Interspecific Competition- involves organisms among different species. (competition in a community) Lioness and hyenas fighting for food
  15. 15. Cooperation • Some organisms help one another for higher chance of survival. Ants are helping one another to protect and sustain their colony.
  16. 16. Symbiosis • An interaction that involves two different kinds of organism, where one is benefited while the other may be benefited, harmed or unaffected. • Examples are mutualism, parasitism and commensalism.
  17. 17. Mutualism The two organisms are benefited. Butterfly drinks nectar from flowers.Butterfly helps the flowers in pollination.
  18. 18. Ants protect aphids from predator Aphids give food to ants. Ants and Aphids
  19. 19. Parasitism • One organism is benefited (parasite) , the other is harmed (host). Man is the host. Leech is the parasite.
  20. 20. Parasitism Ectoparasitism- parasites are found outside the host’s body Endoparasitism- parasites are found inside the host’s body
  21. 21. Commensalism One organism is benefited (commensal) while the other is not affected (host). Shark is the host. Remora is the commensal.
  22. 22. Commensalism Tree is the host. Orchid is the commensal.
  23. 23. Organism A Organism B Mutualism Benefited Benefited Parasitism Benefited (Parasite) Harmed (Host) Commensalism Benefited (Commensal) Not Affected (Host)
  24. 24. Mutualism
  25. 25. Commensalism
  26. 26. Parasitism
  27. 27. Competition
  28. 28. Predation
  29. 29. Cooperation
  30. 30. Predation
  31. 31. Parasitism
  32. 32. Mutualism
  33. 33. Cooperation
  34. 34. Assignment • Bring a full-body picture of yourself, an experiment paper and pencil
