Biotic and abiotic factors

• What is carrying capacity?

  The maximum amount of individuals an area can support sustainably
• What is the lag phase?

  Where interphase taking place, getting ready for cell division
• What is exponential growth?

  Population doubles in a unit time
• What is carrying capacity?

  Stationary phase, stable migration, birth rates and death rates are equal
• What is the death phase?

  A lot more limiting factors
• What are abiotic factors?

  • Water
  • Temperature
  • Light
  • pH
  • Wind speed and direction
  • Space
  • Oxygen concentration
  • Carbon dioxide concentration
  • Nutrients and minerals
• What does water affect?

  Photosynthesis, nutrient uptake and transpiration
• What does temperature affect?

  Enzyme action, endotherms and ectotherms
• What does light affect?

  Provides energy for the ecosystem through photoautotrophs
• What does pH affect?

  Enzyme action
• What are the biotic factors?

  • Competition
  • Predators
  • Parasites and diseases
• What does intraspecific mean?

  Within the same species
• What does interspecific mean?

  Between different species
• What is the competition exclusion principle?

  Where two species initially occupy the same niche, but one has a competitive advantage
• What can the predator prey cycle be impacted by?

  Abiotic, biotic and human factors
