Chapter 2 Slides Presentation Transcript

  • 1. Interactions in Ecosystems 1
  • 2.  Bioticfactors = living things (plants, animals, bacteria, fungi, protists) 2
  • 3.  Abiotic factors = non-living things (air, water, soil, temperature, precipitation, l ight, etc..) 3
  • 4.  Biosphere contains  Biomes Biomes contain  Ecosystems Ecosystems contain  Habitats where a variety of organisms live 4
  • 5.  Ecosystem = a part of a biome in which biotic and abiotic components interact Can be small  tide pools, rotting log Can be large  entire forest Biotic components depend on Abiotic components 5
  • 6. ORGANISM Individual member of a species POPULATION all of the members of a certain species within an ecosystem 6
  • 7. COMMUNITY all the organisms that interact within an ecosystem  All of the biotic factors! ECOSYSTEMpart of a biome in which biotic AND abiotic components interact 7
  • 8.  Organism Population Community Ecosystem 8
  • 9.  Page 24: Questions 1-7 Chapter 2 Review Questions Chapter 2 Vocabulary 9
  • 10.  Producers (autotrophs) 10
  • 11.  Carnivores  Omnivores  Detrivores  Herbivores 11
  • 12.  Relationshipbetween the “eaters” and the “eaten” Predators have adaptations to help them catch prey Prey have adaptations to avoid predators  Spines, shells, camouflage, mi micry 12
  • 13.  Predator-prey cycle  If numbers of prey increase, then numbers of predators increase (more food), which then causes numbers of prey to decrease… and so on 13
  • 14.  Page 29: Questions 1-13 Chapter 2 Review Questions Chapter 2 Vocabulary 14
  • 15.  Symbiotic relationships = interactions between members of two different species  Parasitism meh. Mutualism  Commensalism 15
  • 16.  Both species benefit  Biological example: bees and flowers 16
  • 17.  One species benefits, the other is harmed  Biological example: hookworm in dogs 17
  • 18.  One species benefits, one is not affected  Biological example: barnacles on a whale meh. 18
  • 19.  Page 32: Questions 1-11 Chapter 2 Review Questions Chapter 2 Vocabulary 19
  • 20.  Energy flow = transfer of energy from one organism to another in an ecosystem Energy moves in only ONE direction in an ecosystem ARROWS used to show direction of energy flow Energy is LOST as it moves from one organism to another Original source of energy is the SUN 20
  • 21.  TROPHIC LEVEL = position of an organism within a food chain Trophic levels:  PRODUCERS  produce carbohydrates from CO2, water and energy from the sun  CONSUMERS  get energy by eating producers and/or other consumers 21
  • 22. 22
  • 23.  Most consumers eat more than one type of food and so a web represents a more realistic view of what they eat. Arrows point TOWARDS consumers 23
  • 24.  90% energy loss at each trophic level Less energy reaches higher trophic levels Fewer organisms at higher trophic levels 24
  • 25.  Page 37: Questions 1-11 Page 41: Questions 1-7, 9 & 11 Chapter 2 Review Questions Chapter 2 Vocabulary 25
