Abiotic and biotic

• What are biotic factors?

  Living factors affecting organisms or ecosystems
• How does predation classify as a biotic factor?

  It influences the population of another species
• What are some examples of biotic factors?

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

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

  Light intensity, temperature, and moisture levels
• How does temperature affect photosynthesis?

  Higher temperatures increase enzyme activity
• What happens to animals with increased temperatures?

  They spend less energy staying warm
• What are typical exam questions about biotic and abiotic factors?

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

  Predation, habitat competition, and disease
• What abiotic factors affect clownfish?

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

  They impact the sea anemone, affecting clownfish
• 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)
• How do changes in abiotic factors impact ecosystems?

  • Affect organism survival and growth
  • Influence species interactions and ecosystem dynamics
