National Five Biology: Distribution of Organisms Quiz

Which of the following is NOT a learning objective for this lesson?

• Explain the process of photosynthesis

• Describe abiotic and biotic factors

• Use and construct paired statement keys

• Explain what an indicator species is

Which of the following is an example of an abiotic factor?

• Light intensity

• Disease

• Competition for resources

• Predation

What is the correct term for non-living factors that affect the distribution of organisms?

• Biotic factors

• Environmental factors

• Abiotic factors

• Ecological factors

Which of the following is NOT a biotic factor?

• Predation

• Food availability

• Grazing

• Temperature

What instrument is used to measure light intensity?

• pH meter

• Thermometer

• Moisture meter

• Light meter

How can you minimize the error of standing in the path of light when using a light meter?

• Take the reading quickly

• Stand away from the light source

• Use a different instrument

• Wipe the probe after each use

What is a possible source of error when measuring soil temperature?

• Not allowing the thermometer to stabilize

• Standing in the path of light

• Using a light meter

• Using a moisture meter

Which sampling technique is used for estimating the abundance of plants or slow-moving animals?

• Quadrat

• Thermometer

• Light meter

• Pitfall trap

What is a limitation of using quadrats?

• Depends on human accuracy

• Can only be used for large organisms

• Requires a light meter

• Can only be used for fast-moving organisms

How can you ensure a representative sample when using a quadrat?

• Randomly place the quadrat multiple times

• Use a light meter

• Only use one quadrat

• Place the quadrat in areas with the most organisms
