Biotic factors
Living
Example abiotic factors
Light intensity, temperature, moisture
How to select randomly
Random coordinate generator
Why do we need to place Quadrat more then once
More likely valid results. Not representative of the whole area
Transect how to make more valid
Move tape measure along and repeat
Why place Quadrats in random positions
To prevent bias
Transect steps
Use a large number of Quadrats
Place at regular intervals
Make sure transect runs through different light intensities
For each Quadrat count number of number of dandelions and light intensity
Compare data from both areas
Two environmental factors other then light which effect growth of plant
Temperature
Water
Minerals
