Terms in this set (13)
used to sample things that do not move. A square or grid is placed and the abundance of a particular organism is measured
a line taken across an area where samples are taken systematically along it.

results of a sample that can be incorrect due to the sample not being representative or the method being incorrect
equipment used to sample an abiotic factor e.g. thermometer, pH probe, oxygen probe
Number paired statement key
