1

Mutalism example

both species benefit (+,+) flowers and their insect pollinators

2

commensalism example

one species benefits while the other is neither harmed nor helped (+, 0) squirrels living in trees

3

parasitism example

one species benefits while the other is harmed (+,-) ticks feeding off of deer

4

ecological succession

a change in which new species gradually replace existing ones through inter-specific competition

5

primary succession examples

begins w/ no life an no established soil like a... new volcanic island under a receding glacier a new sand dune


7

secondary succession

occurs after a natural disaster of human disturbance (like a strip mine) soil already exists

11

ecological succession

12

primary succession examples

begins w/ no life an no established soil like a... new volcanic island under a receding glacier a new sand dune


14

secondary succession

occurs after a natural disaster of human disturbance (like a strip mine) soil already exists

15

island biography

is the study of ecological succession of an island island size and distance from mainland are key factors


17

autotroph?

an organism that is able to produce it's own energy/ food usually through photosynthesis

18

Some predators of desert grasses?

mule deer douglass squirrel edith's chekerspot pacific tree frog red-breasted nuthatch pika



21

WHat adaptations to desert grasses have to survive in the desert?

ability to perform photosythesis the ability to not need as much water as other grasses in wetter ecosystems



24

biotic factors include...

all the communities of living organisms

25

abiotic factors

non-living factors, include temp. and rainfall patterns (climate), governed by latitude, altitude, and landforms soil/minerals, required for growth + development energy source (usually sunlight)



28

Water Cycle

the repeated movement of water between the Earth's surface and the atmosphere


30

An ecosystem is healthy when it has

high amounts of biodiversity

31

species richness corresponds with

the number of different species

32

species diversity corresponds with the

relative abundance of species


34

Competitive Exclusion Principle

non-native invasive species will often out-compete and replace native species

35

species richness corresponds with

the number of different species

36

species diversity corresponds with the

relative abundance of species


38

Competitive Exclusion Principle

non-native invasive species will often out-compete and replace native species

39

40

Biomagnification

the increasing concentration of toxic substances within each successive link in the food chain.

41

Examples of Biomes (terrestrial and Aquatic) 3 of each

tropical rain forest termperate grassland savanna coral reefs open sea freshwater lakes and rivers

42

Examples of Co2 Sources? 5

wildfires fossil fuel mining transportation volcanic activity erosion like limestone

43

Examples of CO2 Sinks 3 (only 3)

02 production: produces forest, plants, ocean creatures Co2 dissolved in oceans photosythesis

44

Positive Feedback Loop

the climate warming causes events that contribute to further warming drought---> forest fires ---> more CO2 in atmosphere

45

Negative Feedback Loop

higher CO2= plant photosynthesis more effecient

46

what is Climate Warming causing

many extinctions as animals and plants are not able to survive in rapidly changing conditions



49

what was your biome

woodland shrubland grassland
