  • 1. CHAPTER 4:INTERACTIONBETWEEN LIVINGORGANISMS
  • 2. INTERACTIONBETWEENORGANISMSPrey predator Competition SymbiosisCommensalism ParasitismMutualism
  • 3. Prey-predatorA relationship where an animal captures andeat other animals.Rat is the victim(prey)Snake eats andkills rat(predator)
  • 4. OwlRat(Predator)(Prey)Frog(Predator)Insects(Prey)
  • 5. Predator PreyOwlTigerFrogRatGoat/deerInsect
  • 6. CompetitionCompetition is a relationship where organismscompete with each other for food, light, water,shelter, mate or minerals.Compete for food Compete for light
  • 7. This is Intra-specific competition.Competition among organisms of the same species.
  • 8. This is Inter-specific competition.Competition among organisms of different species.
  • 9. INTERACTIONBETWEENORGANISMSPrey predator Competition SymbiosisCommensalism ParasitismMutualismOrganismslive together
  • 10. Commensalism Commensalism is a relationship between twoorganisms. The commensal benefits from the host.
  • 11. Commensalism (+,0)Remora fishGets- free transport- feeds on foodscraps left by sharkShark-not receive anybenefits or harm
  • 12. Commensalism (+,0)Bird’s nest fern-Grows on a tree-To obtain sunlightTree-not receive anybenefits or harm
  • 13. bBarnacles- gets shelterMussels- Not affected
  • 14. INTERACTIONBETWEENORGANISMSPrey predator Competition SymbiosisCommensalism ParasitismMutualismOrganismslive together
  • 15. MutualismMutualism is an interaction that benefitsboth organisms. (+,+)
  • 16. Mutualism (+,+)Lichen consists of fungi and algae living together.Algae- produce foodFungi- Provide shelter
  • 17. Mutualism (+,+)Nodule(containNitrogen fixingbacteria)- Plant needs nitrogen- But it must be changedto nitrates first.- Nitrogen-fixing bacteriachange nitrogen to nitratesPeanut plant root-Provide shelter and foodbacteria
  • 18. INTERACTIONBETWEENORGANISMSPrey predator Competition SymbiosisCommensalism ParasitismMutualismOrganismslive together
  • 19. Parasitism (+,-) Parasitism is an interaction that benefits theparasites. On the other hand, the host is harmed by theparasites.
  • 20. Parasitism (+,-)Tapeworm- A parasite- Live in human intestine- Obtain food and shelterfrom humanHost (Human)-Loses weight-Becomes weak
  • 21. Parasitism (+,-)Wood fungus- Obtains food andshelter from treeHost (Tree)-Is weakened andmay die
  • 22. Parasitism (+,-)Rafflesia- Obtains food andshelter from treeHost (Tree)-Is weakened andmay die
  • 23. Interaction EffectsPrey-predator + (predator)- (prey)Competition + (stronger organism)- (weaker organism)Commensalism + (the commensal)0 (the host)Mutualism +,+ (both organisms)Parasitism + (the parasite)- (the host)Symbiosis(“Livingtogether’’)Indicator :+  benefits - harm 0  not affected (neither benefit nor harm)
  • 24. Biological controlAttack,destroyThe fruitsOil palm plantation
  • 25. versusBiological controlPesticideWhich method is better to killthe pests and saveenvironment?
  • 26. Biological controlkill- A method of using living things to kill the pests.- Use prey-predator relationship.
  • 27. Biological controlAphids (insects)- destroy the plantLadybird- eat aphids-to save the plant
  • 28. Biological control has many advantages as compared to usingpesticides.Some of them are :a. does not pollute the environmentb. does not kill other pests because naturalenemies are usedc. is cheap and safe to use.Biological control
