recall the use of quadrats to estimate the population size of an organism in two different areas.
-ecosystem is made up of a number of populations which forms the community and the habitat.
- fence separating two different areas of the sand dune. grazed by cattle and ungrazed by cattle.
-we can study both of the sides by counting the number of individuals in the population in each side.
-we can use the technique quadrating -> squares made of any material to form a square grid. (quadrats range from half a meter by half a meter to one meter by one meter)
-quadrats are used to sample the area and count the number of individuals inside the area and will be repeated a number of times to get and estimate of the population size.
- quadrats can be sampled in different locations and they can be compared.
