Biotic and abiotic factors

• 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
• How does temperature affect photosynthesis?

  Higher temperatures increase enzyme activity
• What happens to animals when temperature increases?

  They use less energy to stay warm
• What are typical exam questions about biotic and abiotic factors?

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

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

  Water temperature, oxygen concentration, and acidity
• How do abiotic factors indirectly affect clownfish?

  They influence other species like sea anemones
• What is the role of the sea anemone for clownfish?

  It acts as the clownfish's habitat
• Why is competition for plankton important for clownfish?

  It affects their food availability
• How does light intensity affect ecosystems?

  It influences photosynthesis rates in plants
• What is the impact of carbon dioxide concentration on ecosystems?

  It affects plant growth and photosynthesis
• What is the significance of soil pH in ecosystems?

  It affects nutrient availability for plants
• How does moisture level impact ecosystems?

  It influences plant growth and survival
• What is the relationship between abiotic and biotic factors?

  Abiotic factors influence biotic interactions
• How does wind direction affect ecosystems?

  It influences temperature and moisture distribution
• What is the effect of increased temperature on plant growth?

  It can increase the overall growth rate
• How does increased oxygen concentration affect aquatic life?

  It supports higher metabolic rates in organisms
• What happens when abiotic factors change in an ecosystem?

  They can alter the interactions among biotic factors
• Why is it important to study both biotic and abiotic factors?

  To understand ecosystem dynamics and interactions
• What is the main focus of this video?

  Biotic and abiotic factors in ecosystems
• What are the key differences between biotic and abiotic factors?

  • Biotic factors: Living components affecting ecosystems
  • Abiotic factors: Non-living components affecting ecosystems
• What are the steps to analyze an ecosystem for biotic and abiotic factors?

  1. Identify living organisms present
  2. Determine interactions among organisms
  3. Assess non-living environmental conditions
  4. Analyze how changes affect the ecosystem
