Assessment 3-Nutrient cycling

The cycling of matter is important because

• Matter can be created and destroyed
• Only a limited amount of matter is available so it has to be recycled
• Matter can only be found in a solution
• Bacteria use matter to convert organisms into solar energy

Matter can recycle through the biosphere because

• matter is passed out of the body as waste

• matter is assembled into chemical compounds

• biological systems do not use up matter, they transform it.

• biological systems use only carbon, oxygen, hydrogen, and nitrogen.

Which of the following best describes the importance of biogeochemical cycles?

• They show how certain elements and compounds move through the environment and are continually used and recycled.

• They explain how energy moves through trophic levels of an ecosystem.

• They describe how the adaptations of organisms change based on environmental pressures.

• They chart how biotic changes destroy unstable ecosystems.

The repeated movement of water between Earth’s surface and the atmosphere is called

• the water cycle

• the condensation cycle

• precipitation

• evaporation

How does water transfer when it evaporates from the ocean?

• hydrosphere to atmosphere

• hydrosphere to biosphere

• hydrosphere to geosphere

• atmosphere to hydrosphere

Examine the figure to infer the relationship between condensation and precipitation

• precipitation needs to occur prior to condensation.

• condensation needs to occur prior to precipitation.

• both are parts of the water cycle.

• both b and c describe the relationship.

How is carbon stored in the biosphere? Check all that apply.

• in the atmosphere as carbon dioxide

• underground as fossil fuels and calcium carbonate rock

• in the oceans as dissolved carbon dioxide

• as organic molecules in living and dead organisms found in the biosphere

Carbon cycles through the biosphere in all of the following processes EXCEPT

• photosynthesis

• burning of fossil fuels

• transpiration

• decomposition of plants and animals
