Biotic and Abiotic Factors

• What are biotic factors in an ecosystem?


  Biotic factors are any living factors that affect another organism or shape the ecosystem.
• How does predation serve as a biotic factor?


  Predation influences the population of another species, affecting the ecosystem's balance.
• What are some examples of biotic factors?


  Examples include competition for resources, habitat, disease, and food availability.
• What are abiotic factors in an ecosystem?


  Abiotic factors are all the non-living parts of the environment that can affect organisms.
• What are some examples of abiotic factors?


  Examples include light intensity, temperature, carbon dioxide concentrations, and moisture levels.
• How can an increase in temperature affect plant growth?


  An increase in temperature can increase the rate of photosynthesis, leading to greater plant growth.
• How might temperature changes affect animals in an ecosystem?


  Animals may spend less energy staying warm, allowing more energy for growth or foraging.
• What are the main biotic and abiotic factors affecting a clownfish?


  Biotic factors:

  • Predation by bigger fish or eels
  • Sea anemone as habitat
  • Competition for habitat and food (plankton and algae)
  • Burden of disease

  
  

  Abiotic factors:

  • Water temperature
  • Oxygen concentration
  • Levels of acidity and salt in the water
• How do abiotic factors like light intensity and carbon dioxide concentration indirectly affect clownfish?


  They affect other species like sea anemones, which in turn impact clownfish.
• What is the focus of typical questions regarding biotic and abiotic factors?


  Identifying various biotic and abiotic factors and explaining the effects of their changes.
