Question 1

Aim

Answer 1

To investigate the effect of water velocity on the average species richness of freshwater invertebrates.

Question 2

Underlying 1

Answer 2

The method used was kick Sampling, which is mainly a qualitative sampling technique meaning it can give us infomation on the different species living in an area.

living

Question 3

Method sample

Answer 3

Freshwater invertebrates were stamped at each site using kick sampling and identification keys.

Question 4

Method water

Answer 4

Water velocity was calculated by recording the time taken for a ball to float 2m with a stopwatch, the time and distance was later applied to a speed distance time equation

Question 9

How was average species richness found?

Answer 9

The average species richness was found by finding the species richness of each sample at a site and averaging it.

Plus sample equation
