Question 1

symbiosis

Answer 1

species interactions
1. antagonistic- 1 benefits, 1 harmed
2. mutualism- both benefit
3. competition- 2 species compete for the same source
4. commensalism
5. predation

Question 2

predation

Answer 2

1. fright
2. concealment
3. warning coloration
4. vigilance
5. mimicry

Question 3

mimicry

Answer 3

-batesian- non toxi resembles toxic
-mullerian- number of toxic species coverage on a common pattern, all benefit fro providing a stronger recognition signal to predators

Question 4

intraspecific comp.

Answer 4

individuals of same species

Question 5

interspecific comp.

Answer 5

indviduals of different species

Question 6

interferences comp.

Answer 6

a competitor interferes with another to access a resource

Question 7

exploitation comp.

Answer 7

one competitor is more efficient in using a resource than another

Question 8

competitive exclusion

Answer 8

no 2 species can long coexist sharing the same limiting resource

Question 9

resource partitioning

Answer 9

selection pressures from interspecific comp. can change the ways the competing species use the limiting resource if changes allow
