Biotic Factors

A

Any living factor in an organism’s environment
Ex: Salmon live in water with other fish, algae, and other organisms. Birds may pass through this area.

Q

Detritivores

A

A heterotroph that decomposes organic material and returns the nutrients to soil, air, and water making the nutrients available for other organisms.
Ex. worms, aquatic insects

Q

Decomposers

A

Breaks down dead organisms by releasing digestive enzymes.
Ex: fungi, bacteria

20
Q

Trophic Level

A

Each step in a food chain or food web.

21
Q

Food Chain

A

A simplified model that shows a single path for energy flow through an ecosystem.

22
Q

Food Web

A

A model that shows many interconnected food chains and pathways in which energy flows through a group of organisms.

23
Q

Detritivore vs. Decomposer

A

Both involve making nutrients available for other organisms’s use.
However decomposers break down dead organisms but detritivores decompose organic material.

24
Q

Water Cycle

A

Evaporation: water to water vapor
Condensation: water vapor to water
Melting: ice to water
Freezing: water to ice

25
Q

Nitrogen Cycle

A

Nitorgen fixation removes nitrogen from the its reservoir and converts it into a usable form.
Dentrification converts nitrates in the soil back in the soil back into the reservoir.
Reservoir=atmosphere

26
Q

Phosphorous Cycle

A

Short-term: soil to producers to consumers
Long-term: weathering- the erosion of rocks with phosphorous adds phosphorous to the cycle

27
Q

Carbon/Oxygen Cycles

A

Producers use carbon dioxide to make food then release oxygen during photosynthesis.
Autotrophs and Heterotrophs release carbon dioxide through the air through cellular respiration.
Carbon is in it’s long-term cycle when organic matter is buried under ground and converted to peat, coal, oil, or gas desposits.

28
Q

Limiting Factor

A

A biotic or abiotic factor that restricts the number, distribution, or reproduction of a population within a community.

29
Q

Tolerance

A

An organism’s ability to survive biotic and abiotic factors.

30
Q

Ecological Succcession

A

The process by which one community replaces another community because of changing abiotic and biotic factors.

31
Q

Primary Succession

A

The establishment of a community in an area of bare rock or bare sand, where no topsoil is present.

32
Q

Secondary Succession

A

The orderly change that occurs in a place where soil remains after a community of organisms has been removed.

33
Q

Climax Community

A

A stable, mature ecological community with little change in the composition of species.

34
Q

Weather

A

The atmospheric conditions such as temperature and precipitation at a specific place and time.

35
Q

Latitude

A

Imaginary horizontal lines going from north on the globe to the very south.

36
Q

Climate

A

The average weather conditions in a specific area, determined by latitude, elevation, ocean currents, and other factors.

37

Precipitation: 15-25 cm per year
Temperature: -70-12 degrees C

A

Tundra

38

Precipitation: 30-84 cm per year
Temperature: -54-21 degrees C

Precipitation: 50-130 cm per year
Temperature: 20-30 degrees C

A
