## 1. What 2 things do you need to make sure you get valid results

• Get the data and calculate the mean
• Get the abiotic and biotic data
• Measure the quadrant and calculate the area
• Get biotic data and calculate the mean
1 of 6

## 2. What is a quadrat?

• They are lines of celotape that are placed randomly in the habitat and you can then count the number if species in that quadrat.
• They are 4 square frames that are placed randomly in the habitat and you can then count the number if species in that quadrat.
• They are square frames that are placed randomly in the habitat and you can then count the number if species in that quadrat.
• They are square frames that are placed in a specific co-ordinate in the habitat and you can then count the number if species in that quadrat.

## 4. Why/When would you use a transect quadrat method, rather than the random method?

• If you wanted to Know how many abiotic and biotic relationships there were in a random area you would use te transect quadrat.
• If you wanted to Know how many abiotic and biotic relationships there were in a specific area you would use the transect or quadrat.
• If you wanted to Know how many abiotic and biotic relationships there were in a specific area you would use the transect.
• If you wanted to know how many abiotic and biotic relationships there were in a specific area you would use the quadrat.

## 5. How do you use a quadrat?

• 1. Place 2 tape measures to make an x and y axis 2. Use a scientific calculator to get a random number to make your co-ordinates 3. Go to the 5th random co-ordinate and place your quadrant 4. Record your abiotic and biotic data 5. Calculate means
• 1. Place 2 tape measures to make an x and y axis 2. Use a scientific calculator to get a random number to make your co-ordinates 3. Go to the 1st random co-ordinate and place your quadrant 4. Record your abiotic and biotic data
• 1. Place 6 tape measures to make an x and y axis' 2. Use a scientific calculator to get a random number to make your co-ordinates 3. Go to the 1st random co-ordinate and place your quadrant 4. Record your abiotic and biotic data 5.Calculate means
