Abiotic and Biotic Factors

• What are the two main types of factors discussed in the video?

  Biotic and abiotic factors
• How can biotic factors be described?

  As any living factor that affects another organism or shapes the ecosystem
• What is an example of a biotic factor mentioned in the video?

  Predation
• How does predation influence an ecosystem?

  It can influence the population of another species
• What are some other examples of biotic factors mentioned?

  Competition for resources, habitat, disease, and food availability
• What are abiotic factors?

  All of the non-living parts of the environment that can affect organisms
• What are some examples of abiotic factors listed in the video?

  Light intensity, temperature, carbon dioxide concentrations, moisture levels, wind intensity and direction, pH, and mineral content of the soil
• How can an increase in temperature affect photosynthesis?

  It could increase the rate of photosynthesis because enzymes can work faster
• What might be a consequence of increased temperature for animals?

  They might spend less energy staying warm and use more energy for growth
• What is a typical focus of questions regarding biotic and abiotic factors?

  Identifying these factors and explaining what happens if they change
• What are the main biotic factors affecting a clownfish?

  Predation by bigger fish or eels, the sea anemone as habitat, competition for habitat, and competition for food
• What abiotic factors affect clownfish?

  Water temperature, oxygen concentration, acidity, and salt levels
• How might light intensity and carbon dioxide concentration indirectly affect clownfish?

  They might affect other species like the sea anemone, which in turn affects the clownfish
• What are the key differences between biotic and abiotic factors?

  • Biotic factors:
  • Living components (e.g., plants, animals, bacteria)
  • Affect populations and ecosystems (e.g., predation, competition)

  
  

  • Abiotic factors:
  • Non-living components (e.g., temperature, light, moisture)
  • Influence the environment and living organisms
• What impacts can changes in abiotic factors have on an ecosystem?

  • Changes in temperature can affect:
  • Photosynthesis rates
  • Energy expenditure in animals

  
  

  • Changes in moisture levels can influence:
  • Plant growth
  • Habitat availability for organisms
