100

All living organisms in an area

What is a community?

100

The plants & animals found in a region; based on yearly temp. + precipitation (climate)

What is a Biome?

100

How much salt there is in a body of water, determines which species can survive & usability for drinking

What is Salinity?

100

Plants & animals taking N in and incorporating it into their body

What is Assimilation?

100

Animals that eat secondary consumers or carnivores & omnivores (aka - top/apex predators)

What is Tertiary Consumers?

200

The plants and animals found in a given region (determined by climate)

What is a Biome?

200

nutrient-poor soil (high competition from so many diff. plant species)

What is Tropical RF?

200

Influences how much sunlight can penetrate and reach plants below the surface for photosynthesis

What is Depth?

200

Soil bacteria, microbes & decomposers converting waste & dead biomass back into NH3 and returning it to soil

What is Ammonification?

200

Animals that eat primary consumers or herbivores (aka - carnivores & omnivores)

What are Secondary Consumers?

300

Relationship that benefits both organisms (coral reef)

What is Mutualism?

300

nutrient-poor soil (low temp. & low decomp. rate of dead org. matter)

What is Boreal Forest?

300

Determines which plants & organisms can survive, how much O2 can dissolve into water

What is Flow?

300

Conversion of NH4 into nitrite (NO2-) & then nitrate (NO3) by soil bacteria

What is Nitrification?

300

Animals that eat plants (herbivores)

What are Primary Consumers?

400

One organism using another for energy source (hunters, parasites, even herbivores)

What is Predation?

400
  • nutrient-rich soil (lots of dead org. matter - leaves & warm temp/moisture for decomp.)

What is a temp forest?

400

Area with soil submerged/saturated in water for at least part of the year, but shallow enough for emergent plants

What is Wetland?

400

Conversion of soil N (NO3) into nitrous oxide (N2O) gas which returns to atmosphere

What is Denitrification?

400

(plants) “produce”- really convert sun’s light energy into chemical energy (glucose)

What are Producers?

500

Relationship that benefits one organism & doesn’t impact the other (birds nest in trees)

What is Commensalism?

500

(distance from eq) determines temp. & precip.

What is Latitude?

500

Areas where rivers empty into the ocean

What are Estuaries?

500

Excess fertilizer use can lead to NH3 gas entering atm.

What is Ammonia volatilization?

500

Since energy is needed for growth &  only 10% of energy transfers from one level to the next, only 10% of the biomass can be grown/supported

What is the 10% rule?
