Abiotic and biotic factors ppt

  1. 1. Biotic and AbioticBiotic and Abiotic factors in thefactors in the EcosystemEcosystem
  2. 2. • Level of organization is used to show how organisms interact with each other & their environment
  3. 3. • Abiotic factors = non-living components that affect living organisms • Ex. Temperature, sunlight, rocks • Biotic Factors = all living things or their materials that directly or indirectly affect organisms in its environment (includes interactions) • Ex. Plants, animals, fungi, bacteria
  4. 4. • A(n) ___________ factor is a living (or once living) component of an ecosystem. • A(n) ___________ factor is a non-living component of an ecosystem. biotic abiotic
  5. 5. • An ecosystem is the interaction between __________ and __________ factors abiotic biotic
  6. 6. Biotic AbioticAbiotic
  7. 7. Biotic AbioticBiotic

  11. 11. • Do these abiotic factors affect the biotic parts of an ecosystem? How?
  12. 12. If there is no water…can anything grow or survive? No! If it is extremely cold one winter, will that affect whether an animal makes it? No! So, abiotic and biotic DO affect each other. EvenSo, abiotic and biotic DO affect each other. Even though water and temperature arenthough water and temperature aren’t living things,’t living things, they DO affect living things!they DO affect living things!
  13. 13. Biotic & Abiotic Influences
  14. 14. Squirrels Trees Fish Air Water
  15. 15. Bacteria Temperatu re Squirrels Flowers Deer Trees Fish Soil Air Minerals Water Sun Grass
  16. 16. • What abiotic factors are important for a plant to grow?
  17. 17. • Provides warmth to living organisms • Provides solarenergy (light) for green plants to make their own food • The number of hours of daylight triggers seasonal events, such as: -plants flowering -birds migrating
  18. 18. • Important forlife processes of all living things (plants and animals) such as: -distributing food particles through their bodies -digesting food • Important fororganisms that live underwater, such as: -trout -whales -algae
  19. 19. • Provides oxygen (O2), which animals breathe • Provides carbon dioxide (CO2) for plants to use to make their own food
  20. 20. • Provides a home for many animals that live underground -earthworms • Provides nutrients for plants • Plants grow in soil
