abiotic & biotic factors

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

  Biotic and abiotic factors
• How are biotic factors defined in the context of ecosystems?

  Living factors that affect other organisms
• What do abiotic factors refer to in an ecosystem?

  Non-living parts of the environment
• 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 when the temperature increases?

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

  Identifying factors and explaining changes
• What biotic factors affect a clownfish living by its sea anemone?

  Predation, habitat competition, and food competition
• What abiotic factors are relevant to a clownfish's environment?

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

  They affect the sea anemone, impacting clownfish
• What are the key differences between biotic and abiotic factors?

  • Biotic factors: Living components (e.g., predation, competition)
  • 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 interactions among species
  • Change ecosystem dynamics and health
