What are terrestrial biomes?

100
A living component in an ecosytem.

What is a biotic factor?

100

The power source of the hydrologic cycle.

What is the Sun?

100

The rate at which solar energy is converted into organic compounds via photosynthesis over a unit of time.

What is primary productivity?

100

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?

200

A vital natural resource that is found in limited supply in aquatic biomes.

What is drinking water?

200

One species benefits while the other is neither benefited nor harmed.

What is commensalism?

200

The major reservoir of the nitrogen cycle.

What is the atmosphere?

200

The total rate of photosynthesis in a given area.

What is gross primary productivity?

200

A variety of organisms occupy the same feeding position in a food pyramid.

What is a trophic level?

300

The single most important difference between the marine, freshwater, and estuary biomes

What is Salinity (dissolved salt)?

300

The unique set of resources used by a species, which includes interactions with other species.

What is (a) niche?

300

This biogeochemical cycle has no atmospheric component.

What is the phosphorus cycle?

300

What is 100 J/m2/day

300

The scientific law that is demonstrated in biogeochemical cycles, food chains, food webs, etc.

What is the Law of Conservation of Matter or Energy?

400

The factors that characterize terrestrial biomes.

What are annual temperature and precipitation?

400
A species on which other species in an ecosystem largely depend, if it were removed the ecosystem would change drastically.

What is a keystone species?

400

The two carbon cycle processes that exchange carbon in living things.

What are photosynthesis and cellular respiration?

400

The rate of energy storage by photosynthesizers in a given area, after subtracting the energy lost to respiration.

What is net primary productivity?

400

Amount of energy available to a secondary consumer, if 15,000 kcal of chemical energy is stored in organic compounds. 

What is 150 kcal?

500

An ecosystem where water covers the soil or water is near the surface of the soil

What are wetlands?

500

When species use limiting resources in different ways, places, or times to reduce competition.

What is resource partitioning?

500

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?

500

The 3 factors that impact net primary productivity.

What are water availability, temperature, and nutrient availability?

500

An ecological event that involves changes to the structure of an ecosystem resulting from changes in animals or plants.

What is a trophic cascade?
