100

A living component in an ecosytem.

Biotic factor

100

The power source of the hydrologic cycle.

 the Sun

100

What is primary productivity?

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

100

Which trophic level has the greatest amount of biomass?

1st trophic level

200

The factors that characterize terrestrial biomes.

What are annual temperature, precipitation, [and plant growth]?

200

An interaction in which one organism lives on or in another, often referred to as the host

Parasitism

200

The major reservoir of the nitrogen cycle.

 atmosphere

200

What is net primary productivity?

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

200

If 10,000 kcal of energy is available at the level of the producers, what is the amount of energy available at the level of tertiary consumers?

10 kcal

300

The 4 zones of the ocean.

What are intertidal, photic, aphotic, and benthic?

300

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

commensalism

300

**FALL FOLIAGE TRIPLE**

This biogeochemical cycle has no atmospheric component.

 phosphorus cycle

300

The NPP of an ecosystem is 1 kg C/m2/year, and the energy needed by the producers for their own respiration is 1.5 kg C/m2/year. The GPP of such an ecosystem would be

2.5 kg C/mr/year

300

Organisms occupying the same feeding position in a food web.

What is a trophic level?

400

Small inputs of this substance, commonly a limiting factor in aquatic ecosystems, can result in algal blooms and dead zones.

phosphorus

400

Two species living in a long-term association with one another where at least one species is benefiting from the relationship

Symbiosis

400

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

photosynthesis and cellular respiration

400

Which aquatic biome has the lowest net primary productivity, measured as kilocalories of energy produced per square meter per year?

Open ocean

400

** DAILY DOUBLE**


What is it called when a top-level predator is removed from an ecosystem, and there is a ripple effect throughout the ecosystem?

Trophic cascade 



500

The characteristics that define aquatic biomes.

What are salinity, depth, and water flow?

500

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

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.

nitrogen fixation

500

The 3 factors that impact net primary productivity.

What are water availability, temperature, and nutrient availability?

500

What do the first and second laws of thermodynamics state?

1. Energy cannot be created or destroyed.

2. When energy is converted from one form to another, a less useful form results (energy quality). Energy cannot be recycled to a higher quality.
