Flashcards in Chapter 54 - Community Ecology Deck (26):
1

Cryptic Coloration

camoflage

2

Aposematic Coloration

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

3

Beatesian mimic

a harmless species mimics a harmful one

4

Müllerian mimic

2 dangerous species mimic each other

5

Defenses plants have against herbivores

chemical toxins or structures such as spines and thorns

6

Parasitism

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

7

3 types of symbiosis

mutualism, commensalism, facilitation

8

Richness of a community

number of different species in a community

9

Relationship between a food chain and a food web

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

10

Trophic Level

feeding level

11

Limits the nubmer of trophic levels within a community

energy (transfers) and stability

12

dominant species

most abundant or collectively have largest biomass

13

Keystone predator

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
