• 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 abiotic factors?

  Non-living parts of the environment affecting organisms
• Which factors are included in abiotic factors?

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

  It increases the rate of photosynthesis
• What happens to animals with increased temperature?

  They spend less energy staying warm
• What biotic factors affect a clownfish by its sea anemone?

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

  Water temperature and oxygen concentration
