Key factors affecting distribution

• What are keys used for in biology?

  To identify creatures
• What is a transect in ecological studies?

  A method to study distribution areas
• What are the steps involved in conducting a belt transect?

  1. Mark out a line
  2. Place samples along the line
  3. Record observations
  4. Analyze the data
• What can quadrats be used for in ecological studies?

  To study the distribution of organisms
• What types of organisms might be found on a woodland floor?

  Worms, insects, spiders, centipedes
• How many pairs of legs does a centipede have?

  Over 15 pairs of legs
• What are biotic factors in an environment?

  Factors related to living things
• What are abiotic factors in an environment?

  Non-living factors affecting organisms
• How do biotic factors affect the distribution of organisms?

  A new species may outcompete existing ones
• How do abiotic factors affect the distribution of daisies?

  Daisies thrive in areas with more light
• What abiotic factors can be measured to study organism distribution?

  • Light intensity (using a light sensor)
  • Temperature (using a thermometer)
  • Soil pH (using a pH monitor)
  • Soil moisture (using a moisture meter)
• Why are identification keys important in ecological studies?

  They help identify organisms during sampling
• What is the significance of recording different organisms found during sampling?

  It helps in understanding biodiversity
