Chapter 54 - Community Ecology

Question 1

Cryptic Coloration

Answer 1

camoflage

Question 2

Aposematic Coloration

Answer 2

bright colors seem to act as a defense against predators because they usually signal a chemical defense

Question 3

Beatesian mimic

Answer 3

a harmless species mimics a harmful one

Question 4

Müllerian mimic

Answer 4

2 dangerous species mimic each other

Question 5

Defenses plants have against herbivores

Answer 5

chemical toxins or structures such as spines and thorns

Question 6

Parasitism

Answer 6

a parasite derives nutrients from a host (usually harms host)

Question 7

3 types of symbiosis

Answer 7

mutualism, commensalism, facilitation

Question 8

Richness of a community

Answer 8

number of different species in a community

Question 9

Relationship between a food chain and a food web

Answer 9

a species from a food chain could weave into the food web at more than one trophic level

Question 10

Trophic Level

Answer 10

feeding level

Question 11

Limits the nubmer of trophic levels within a community

Answer 11

energy (transfers) and stability

Question 12

dominant species

Answer 12

most abundant or collectively have largest biomass

Question 13

Keystone predator

Answer 13

exert a strong control on the community because of their strong ecological role (not necessarily dominant)

comparing populations where they do and don’t exist
