What is random sampling used for
To compare the numbers of organisms in different areas using a quadrant
What is a quadrant
A wooden or plastic or square
What can this technique(random sampling) be used to sample
Plants or slow moving animals
How do you calculate total population size
(Total area / area sampled) *number of organisms of that species counted in that sample
What is a transect
A line such as a tape measure or piece of rope
The moon
Why do we sample along a transect
To see how the number of organisms change across a habitat. Doing this give us valid data on how many numbers of different species change across
How do you get a more accurate result using a quadrant
Place it à large amount of times
Why does one use a quadrant
To count the number of organisms in an area
