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.
3. How do you use a transect (method)?
- Run a tape measure across your qudrat Place your quadrant at regular intervals Record your abiotic and biotic data Calculate means
- Run a tape measure across your area Place your quadrant at regular intervals Record your abiotic and biotic data
- Run a tape measure across your area Place your quadrant at regular intervals Record your abiotic and biotic data Calculate means
- Run a tape measure across your area Place your quadrant at random intervals Record your abiotic and biotic data Calculate means
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?
