A diagram that shows the amount of energy that moves from one feeding level to another in an ecosystem is called a(n)

• food chain.

• succession.

• food web.

• energy pyramid.

The processes of evaporation, condensation, and precipitation make up the

• food web.

• water cycle.

• carbon and oxygen cycles.

• nitrogen cycle.

“Free” nitrogen gas is changed into a usable form of nitrogen in the process called

• primary succession.

• condensation.

• nitrogen fixation.

• legumes.

Wind, water, and living things are three means of

• dispersal.

• decomposition.

• succession.

• continental drift.

The type of biome that exists in an area is determined by its

• weather conditions.

• climate conditions.

• food webs.

• exotic species.

The biome which receives less than 25 centimeters of precipitation a year is the

• desert.

• rainforest.

• savanna.

• boreal forest.

An extremely cold, dry land biome is the

• tundra.

• boreal forest.

• deciduous forest

• neritic zone

Succession is the series of predictable changes that occur over time in a

• species.

• population.

• community.

• food chain.
