biotic & abiotic 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 affecting another organism
• What is an example of a biotic factor?

  Predation
• What can biotic factors influence in an ecosystem?

  The population of another species
• What are some examples of biotic factors mentioned?

  Competition, disease, food availability
• What are abiotic factors?

  Non-living parts of the environment
• What are some examples of abiotic factors?

  Light intensity, temperature, moisture levels
• How does an increase in temperature affect photosynthesis?

  It increases the rate of photosynthesis
• What might happen to animals with increased temperatures?

  They may use more energy for growth
• What are typical exam questions about biotic and abiotic factors?

  Identifying factors and explaining changes
• What biotic factors affect a clownfish?

  Predation, habitat competition, disease
• How do light intensity and carbon dioxide concentration indirectly affect clownfish?

  They affect the sea anemone, impacting clownfish
• What abiotic factors affect a clownfish?

  Water temperature, oxygen concentration, acidity
• What is the role of the sea anemone for clownfish?

  It acts as the clownfish's habitat
• What happens to clownfish if their habitat is threatened?

  They may face competition for resources
• How do abiotic factors influence biotic factors in an ecosystem?

  They affect the living conditions for organisms
• What are the key differences between biotic and abiotic factors?

  • Biotic factors: Living components (e.g., animals, plants)
  • Abiotic factors: Non-living components (e.g., temperature, light)
• What impacts do changes in abiotic factors have on ecosystems?

  • Affect organism survival and growth
  • Influence species interactions and competition
  • Alter habitat conditions and resource availability
• What are the main biotic and abiotic factors affecting clownfish?

  Biotic factors:

  • Predation by larger fish
  • Competition for habitat and food
  • Disease

  
  

  Abiotic factors:

  • Water temperature
  • Oxygen concentration
  • Acidity and salinity levels
