3.3 study guide

Question 1

Ecological Succesion

Answer 1

The process by which an community and enviorment is formed

Question 2

Primary succession

Answer 2

Egological Succesion when pioneer species have to try and build an envorment from nothering

Question 3

seocondary succestion

Answer 3

egoclogical succesion when species have to rebuild a ecosystem from the remains of a destroyed one.

Question 4

Pioneer Species

Answer 4

A species that colonizes a barren wasteland to get the ball rolling on creating an ecosystrem

Question 5

Climax Species

Answer 5

The species that lives at the height of an ecosystem, oak trees, trees, trees, and cactus are all Climax species of plant.

Question 6

Species Richness

Answer 6

How many species are in a certain area

Question 7

Species eveness

Answer 7

The ratio of species to different species in an area

Question 8

Genetic Divesrtisy

Answer 8

the diversity within a species

Question 9

Ecological Diversity

Answer 9

the diversity within an ecosystem

Question 10

Keystone Species

Answer 10

The species that keeps the Ecosystem in check via predation on something that if left unchecked would ruin the ecosystem´s diversity.

Question 11

Invasive species

Answer 11

Species not natural to an ecosystem and thus don have any natural predators and thus take over an ecosystem and ruin the diversity.

Question 12

If there is a community with 5 species

Species A: 3
Species B: 7
Species C: 1
Species D: 2
Species E: 5
Total: 18

How do you calculate the Shanon-Wiener Diversity and the evenness

Answer 12

Pi= Species A: .17
Species B: .39
Species C: .06
Species D: .11
Species E: .28

ln(Pi) Species A: -1.77
Species B: -0.94
Species C: -2.81
Species D: -2.21
Species E: -1.27

Pi*ln(Pi)= Species A: -0.30
Species B= -0.37
Species C= -0.17
Species D: -0.24
Species E: -0.36

H= 1.44

E= 0.89
