sampling

Question 1

what is sampling

Answer 1

estimating the number of individual organisms present in a particular area, abundance of species can be known

Question 2

Answer 2

particular characteristics, e.g. height of what
representative of the whole

Question 3

line transect

Answer 3

line placed along the ground and samples taken at specified points

qualitative

Question 4

Answer 4

two parallel lines - continuous samples are taken along the belt using a quadrat
quantitative

Question 5

systematic belt transect

Answer 5

one line with quadrat used at specified intervals, allows for more rapid data collection

Question 6

species density

Answer 6

indicates how many individuals of that species there are per unit area
number of individual counted across all quadrats is divided by the total area of all quadrat

Question 7

species frequency

Answer 7

probability that the species will be found within any quadrat in the sample area
no of quadrat of the species was present in is divided by the total number of quadrats and then multiplied by 100
