Question 7

Predation

Answer 7

+/-

Question 8

Competition occurs

Answer 8

-inter/intra specifically-over resources

Question 9

Outcomes of completion

Answer 9

CoexistenceOne or the other becomes extinct

Question 10

What was the Gause experiment?

Answer 10

Grew yeast in competitionStarted with isolated growth then grew them together and one species went extinct

Question 11

Gause’s hypothesis-the competitive exclusion principle

Answer 11

No two species can occupy the same ecological niche simultaneously (complete competitors)

Question 12

Niche (fundamental- , realized-)

Answer 12

Biological role of an organism within the environment”n-dimensional hyperspace” it occupiesFundamental- all possible biological spacesRealized- actual space occupied due to constraints

Question 13

Basic outcome of competitive exclusion principle

Answer 13

One species gets kicked out

Question 14

Aphytis

Answer 14

Genus for wasps

Question 15

Difference between genus and species

Answer 15

Genus is one level up ad it’s always capitalized when species i not

Question 16

List the order of the wasps they introduced to take care of orange pests

Answer 16

ChrysomphaliLinganensisMelinus

Question 17

What happened in the orange pest introduction after each wasp was introduced

Answer 17

Chrysomphali removed pests but not allLinganensis introduced to increase efficiency but competitively excluded ChrysomphaliMelinus introduced to displace Linganensis

Question 18

After being excluded, there were still species of Linganensis on the coast, how come?

Answer 18

No competition with others on the coast

Question 19

Situations where competitive exclusion does not occur

Answer 19

Unstable environmentsFluctuating environmentsNo competition
