In the required practical sampling organisms what do you investigate.
• Describe how to measure the population size of a common species in a habitat. • Describe how to use sampling techniques to investigate the effect of a factor on the distribution of this species.
Firstly , you must estimate the …
total population of the plants eg. daisies in the area like a filed.
When random sampling we can use a …
quadrat.
To estimate the total population in area using quadrats you can …
calculate the number of species in the quadrat multiply before multiplying the number of species and the area of the quadrat to equate the entire area.
In area that are affected by light intensity we may have to use a …
transect and a quadrat to measure the number of daisies at equal intervalsof the transect as well as the light intensity
To measure light intensity with a …
light meter
It may be that light intensity is not the only abiotic ——- that is affecting the number of species.
