Back 1

A trophic level.

Front 2

Only ten percent of the engergy stored in an organism can be passed on to the next trophic level Of the remaining energy, some is used for the organsism's life processes, and the rest it:

Back 3

population.

Front 4

The organization of an ecosystem is as follows:

Back 6

Carnivore, and consumer.

Front 7

Biogeochemical cycling ensures that:

Back 7

nutrients will be circulated throughout the biosphere.

Front 8

A snake that eats a frog that has eaten an insect that fed on a plant is a what level consumer?

Back 8

Third.

Front 9

What is an ecological model of the relationships that form a network of complex interactions among organisms in a community from producers to decomposers?

Back 9

Food web.

Front 10

How is carbon stored in the biosphere?

Back 10

In oceans, underground, and in the atmosphere.

Front 11

Plant eating animals such as cows are called:

Ground water, when taken up by the roots of plants, eventually reenters the atmosphere by the process of __________________.

Back 12

Precipitation.

Front 13

In the water cycle shown, the process of _________________________ occurs between evaporation and precipitation.

Back 13

Condensation.

Nutrients.

Front 18

Autotrophs capture energy from sunlight or ____________________ to produce food.

Back 18

Chemicals.

Front 19

When individuals in a population reproduce at a constant rate, it is called:

Back 19

exponential growth.

Front 20

Why does Earth have three main climate zones?

Back 20

There are differences in latitude and, thus, the angle of heating from the sun.

Which biome is characterized by very low temperatures, little precipitation, and permafrost?

Back 21

Tundra.

Front 22

A symbiotic relationship in which both species benefit is:

Back 22

mutualism.

Temperature, rainfall, soil type, and plant life are all abiotic factors that effect an ecosystem, except for:

Back 23

plant life.

Front 24

Climate conditions in a small area that differ significantly from the climate of the surrounding area are called:

Back 24

microclimates.

Front 25

What is one difference between primary and secondary succession?

Back 25

Secondary succession begins on soil and primary succession begins on newly exposed surfaces.
