Introduction To Ecology

Question 1

Basic organization

Answer 1

Biosphere to biomes to ecosystems to communities to populations to individuals

Question 2

6 major terrestrial biomes

Answer 2

TRF, desert, tundra, deciduous forest, coniferous forest, grasslands

Question 3

What separates the biomes?

Answer 3

Temperatures, water/precipitation, soil

Question 4

Aquatic biomes

Answer 4

Fresh or salt, estuaries

Question 5

Estuaries

Answer 5

Any where freshwater meets salt water

Question 6

Marine zones

Answer 6

Intertidal/ neretic, open sea/ oceanic, open sea/ plelagic, deep sea/ benthic

Question 7

Intertidal/ neretic

Answer 7

Highly photic has contact with coast

Question 8

Open sea/ oceanic

Answer 8

Photic but no contact with coast

Question 9

Open sea/ pelagic

Answer 9

Non photic no contact with land

Question 10

Deep sea/ benthic

Answer 10

Non-photic cold temps and high pressure

Question 11

Marine zones are based on 2 main trait

Answer 11

Depth - light, pressure, temp

Contact with coast

Question 12

Energy

Answer 12

Tropic

Question 13

What governs the type of abundance and relationship between living and non living?

Answer 13

Available energy

Question 14

Trophic levels

Answer 14

Primary producers, primary consumers, secondary consumer, tertiary consumer

Question 15

Primary producers

Answer 15

Tropic level that supports all others like autotrophs

Question 16

Primary consumers

Answer 16

Herbivores

Question 17

Secondary consumer

Answer 17

Carnivores and omnivores

Question 18

Tertiary consumers

Answer 18

Carnivores and omnivores

Question 19

Clean up crew

Answer 19

Detritivores, decomposers,

Question 20

Detritivores

Answer 20

Aka scavengers, larger will be resulted on energy pyramid as secondary consumer because of size

Question 21

Decomposers

Answer 21

Small does not get regulated on energy pyramid because of size

Both heterotrophs that feed on non living organic matter

Question 22

Trophic structure/levels

Answer 22

Feeding relationships in an ecosystem as trophic means nourishment

Question 23

Food chain

Answer 23

Trophic level food pathway linear

Question 24

Food web

Answer 24

Many food chains

Question 25

Ecological efficiency

Answer 25

% of transferred from one trophic level to the next 10% gets through called 10% law multiplication loss per level

Question 26

Pyrimid of energy/productivity

Answer 26

Show amount of retained and available energy per trophic level measured in Jules

Question 27

Pyramid of biomass

Answer 27

Shows actual weight of what each trophic level contains

Question 28

Pyramids of numbers

Answer 28

Shows actual number of each type of organism on each trophic level

Question 29

Population growth model

Answer 29

Idealized | Called r population j curve

Question 30

Logistic model

Answer 30

Realized | Called k populations s curve

Question 31

R selected strategies to increase biotic potential

Answer 31

Short maturation and lifespan Many smaller offspring No little parental care High death rate

Question 32

K selected strategies to increase biotic potential

Answer 32

Long maturation and lifespan Few larger offspring Extensive parental care Low death rate

Question 33

Population limiting factors environmental resistance

Answer 33

Density dependent factors in density independent factors lead to adaption

Question 34

Density dependent factors

Answer 34

Limited food water shelter predation, disease

Question 35

Density independent factors

Answer 35

Weather or climate

Question 36

Factors lead to what

Answer 36

K='max # of individuals an area can sustain/ carrying capacity

Question 37

Ecology

Answer 37

Study of all components abiotic and biotic within a defined area
