Section 8

Question 1

stratification

Answer 1

vertical/horizontal, distributions

Question 2

species abundance

Answer 2

relative number of species in a community

Question 3

species richness/diversity

Answer 3

number of present species

Question 4

niche structure

Answer 4

quantity of ecological niches available

Question 5

structure of community

Answer 5

stratification, species abundance, species richness/diversity, niche structure

Question 6

highest biodiversity structures

Answer 6

rainforest and deep sea

Question 7

intraspecific competition

Answer 7

direct competition between members of the same species

Question 8

territoriality

Answer 8

exhibited by organisms patrolling/marking boundaries

Question 9

interspecific competion

Answer 9

competition betwen members of two varied species

Question 10

interference competition

Answer 10

when one species limits another’s access to resources

Question 11

exploitaton competition

Answer 11

species haver equal access but differ in rates of exploitation of that resource

Question 12

symbiosis

Answer 12

long lasting relationships shared between species living in intimate association

Question 13

competitive exclusion principle

Answer 13

aka Gausses’ competitive exclusion principle
no two species can occupy same niche indefinitely in a habitat where limited resources available; their niches can’t overlap for long, one must be excluded

Question 14

natural predation

Answer 14

good for population, weeds out sick and dying, can improve gene pool of prey

Question 15

adaptations of carnivorous predators

Answer 15

swiftness, good eye-sight, vibration detection, camouflage, etc.

Question 16

characteristics of prey

Answer 16

swiftness, heightened sense of smell, protective she//skin, camouflage, etc.

Question 17

ecological succession

Answer 17

aka order of events
unique to each biome, but predictable- primary and secondary
beginning of habitat
1. early successional species
2. middle successional species
3. late successional species
4. wilderness species

Question 18

primary

Answer 18

begins in mostly lifeless area

1. pioneer species (moss and lichens) makes soil

Question 19

secondary

Answer 19

area already has soil, occurs on cut down/burned forests

Question 20

ecosystem stability

Answer 20

inertia, constancy, resiliance

Question 21

inertia

Answer 21

ability to resist disturbances/changes

Question 22

constancy

Answer 22

ability to exist within resource availability

Question 23

resiliance

Answer 23

capability of ecosystem to recover after disturbance

Question 24

intermediate disturbance hypothesis

Answer 24

high biodiversity exists in area that frequently experience mild to moderate disturbances
