Show transcript
Abiotic factors such as light levels, temperature, soil moisture and pH can be measured.
Transects can be used to investigate the effects of a changing factor on the distribution and abundance of organisms.
A transect can be placed along a gradient of a factor (e.g. from shade to full sunlight).
A belt transect uses quadrats placed along the straight line to measure distribution and abundance.
