R selected live long, high parental investment.
K species live short, low parental investment
400

Explain how the phylums are grouped in the Linnean classification system using an example from Kingdom and Species
Starting from broad characteristics to most similar
500
What is the name of the relationship in which both species benefit, give an example.
Mutualism, coral and zooxanthallae
500
Compare the differences in traits between the species found on the far left of the cladogram when compared to the species found on the far right
The species on the far right possess all of the traits shown on the cladogram, whilst the species on the far left only possesses the first shared trait shown (in this example, vertebrate)

When conducting stratified sampling, what should be accounted for when collecting data
The size of the zones, larger zones should have a greater number of samples taken when compared to smaller zones
