Ecology

Terrestrial Biomes

100

Biome with the highest biodiversity and productivity.

What is tropical rain forest?

200

Tropical grasslands with scattered trees.

What are savannas?

300

Event such as a storm, fire, or human activity that changes a community, removing organisms from it and altering resource availability.

What is disturbance?

400

Dominated by shrubs and small trees. Some of the shrubs produce seeds that will germinate only after a hot fire. Occurs in midlatitude coastal regions.

What is chaparral?

500

Two factors that determine a biome's productivity.

What are temperature and moisture/precipitation?

Aquatic Biomes

100

Marine zone dominated by phytoplanktons.

What is photic zone?

200

Marine zone with the lowest rates of primary productivity (photosynthesis).

What is abyssal zone?

300

Lake zone absent in a very shallow lake.

What is aphotic zone?

400

Primary limiting factor for aquatic productivity.

What is light availability?

500

Periodically submerged and exposed by the tides, twice daily on most marine shores.

What are intertidal zones?

Population Ecology

100

A localized group of organisms that belong to the same species.

What is a population?

200

The maximum population size that a particular environment can support.

What is carrying capacity?

300

The most common type of dispersion in nature.

What is clumped?

400

The relative number of individuals of each age in the population.

What is age structure?

500

The amount of land and water area required by each person, city, or nation to produce all the resources it consumes and to absorb all the waste it generates.

What is ecological footprint?

Food Chain/Web

100

Animals that only eat plants

What is an herbivore

200

All of the food chains in an ecosystem

What is a food web

300

Animals that eat plants and animals

What is an omnivore

400

 The percentage of energy stored in a trophic level that can be converted to matter in the next trophic level

What is 10%

500

Organisms that make their own food 

What are autotrophs

Ecosystem Ecology

100

Recycle chemical nutrients to a form capable of being used by autotrophs.

What are decomposers?

200

Caused by excessive nutrient runoff into lakes.

What is eutrophication?

300

Nitrogen form that is available to plants.

What is nitrate?

400

High levels of pesticides found in birds of prey.

What is biological magnification?

500

The percentage of production transferred from one trophic level to the next.

What is trophic efficiency?
