Biomes
Examples include taiga, shrubland, and tundra.
What are terrestrial biomes?
What is a biotic factor?
The power source of the hydrologic cycle.
What is the Sun?
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?
One species benefits while the other is neither benefited nor harmed.
What is commensalism?
The major reservoir of the nitrogen cycle.
What is the atmosphere?
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?
The unique set of resources used by a species, which includes interactions with other species.
What is (a) niche?
This biogeochemical cycle has no atmospheric component.
What is the phosphorus cycle?
The units for primary productivity.
What is energy/area/time?
Organisms that eat the secondary consumers
What are tertiary consumers
The factors that characterize terrestrial biomes.
What are annual temperature, precipitation, [and plant growth]?
A specialized type of predator that lays eggs inside other organisms, referred to as its host.
What is a parasite
The two carbon cycle processes that exchange carbon in living things.
What are photosynthesis and cellular respiration?
The rate of energy storage by photosynthesizers in a given area, after subtracting the energy lost to respiration.
What is net primary productivity?
The laws that explain the loss of energy that occurs when energy moves from lower to higher trophic levels.
The characteristics that define aquatic biomes.
What are salinity, depth, and water flow?
When species use limiting resources in different ways, places, or times to reduce competition.
What is resource partitioning?
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?
The 3 factors that impact net primary productivity.
What are water availability, temperature, and nutrient availability?
An ecological event that involves changes to the structure of an ecosystem resulting from changes in animals or plants.
What is a trophic cascade?
