Biomes
Examples include taiga, shrubland, and tundra.
What are terrestrial biomes?
The major reservoir of the nitrogen cycle.
What is the atmosphere?
largest water reserve
What is Ocean?
The rate at which solar energy is converted into organic compounds via photosynthesis over a unit of time.
What is primary productivity?
A model of an interlocking pattern of food chains that depicts the flow of energy and nutrients in two or more food chains.
What is a food web?
A vital natural resource that is found in limited supply in aquatic biomes.
What is drinking water?
microorganism responsible for denitrification
What is bacteria?
The power source of the hydrologic cycle.
What is the Sun?
The total rate of photosynthesis in a given area.
What is gross primary productivity?
Organisms occupying the same feeding position in a food web.
What is a trophic level?
The 4 zones of the ocean.
What are intertidal, photic, aphotic, and benthic?
one long-term carbon reservoir
What is sedimentary rock or Fossil Fuels?
plants absorbing NH4 into their roots
What is Assimilation?
The units for primary productivity.
What is energy/area/time?
The scientific law that is demonstrated in biogeochemical cycles, food chains, food webs, etc.
What is the Law of Conservation of Matter or Energy?
The factors that characterize terrestrial biomes.
What are annual temperature, precipitation, [and plant growth]?
The two carbon cycle processes that exchange carbon in living things.
What are photosynthesis and cellular respiration?
This biogeochemical cycle has no atmospheric component.
What is the phosphorus cycle?
The rate of energy storage by photosynthesizers in a given area, after subtracting the energy lost to respiration.
What is net primary productivity?
percent of energy from one trophic level that makes it to the next trophic level
What is 10%
The characteristics that define aquatic biomes.
What are salinity, depth, and water flow?
The process in which atmospheric nitrogen is converted into a form of nitrogen (primarily ammonia) that is available for uptake by plants.
What is nitrogen fixation?
limiting nutrient in the freshwater biome
What is Phosphorous?
Net Primary Productivity in the Rainforest Biome if the producers have 18,000Kcal/m2/year and the GPP is 30,000kcal/m2/year
What is 12,000kcal/m2/year?
amount of energy available to secondary consumers if producers have 100,000J
What is 1,000J?
