CH 2 Intro to Ecology Review

_________ are the basis of energy in an ecosystem.

An Estuary is a land environment that organisms depend upon for

The waters of the earth are the

Studying a virtual ecosystem on a computer is called

Ecologists study organisms by observation, quadrat sampling, and modeling.

A single sequence of feeding relationships is called a 

Organisms who return vital nutrients to the environment are called

Primary Consumers are also called

Which organism eats plants and animals?

Feeds on dead or decaying matter.

Producer--> Herbivore--> Carnivore-->Decomposer, is an example of a

The variety and number of all species in an ecosystem is referred to as

Forming sugars through a process using chemicals instead of sunlight is

Deciduous trees 

Includes all Earth systems.

Tundra and Taiga biomes both have long winters.

Long-term pattern of weather.

Total of all living and non-living things in same area.

Producer--> Herbivore--> Carnivore--> Carnivore.  How many Trophic Levels are shown here?

Study of the interactions among organisms is

An organism that has an unusually large effect on its ecosystem.

This BGC cycle helps convert gaseous N into ammonia.

Organisms who must eat plants or animals for energy are

Organism who eats a wide variety of foods is known as a

All non-living components of an ecosystem.

There is less energy in each trophic level than the one below because energy is lost as

Major regional or global community of organisms.

Much of the life in a rain forest lives in the upper branches called the

Herbivores are always the first trophic level, the bottom of the food chain.

Model showing networks of feeding relationships.

Where does most of the phosphorous cycle take place?

The air surrounding the earth is known as the

Biome having hot summers, cold winters, and precipitation year around.

The tropical zone which includes the rain forest, is located at the

Living components of an ecosystem.

What level of organization in ecology is defined by climate and plant communities?

Organisms who make food are called

Sometimes cold, sometimes hot, very dry climate.

Energy Pyramid shows how available energy is distributed among the ecosystem.

Communities on a mountainside differ with elevation.

All the alligators living in the same area is an example of a

The total dry mass of organisms in an area.

The biogeochemical cycle moving water from the surface through evaporation to the atmosphere is

Which biogeochemical cycle includes fossil fuels?

Earth has climate zones due to uneven ___________ of the Earth's surface.
