The Cycles Of Matter (Assignment)

What is a biogeochemical cycle? A.) A process by which bacteria convert nitrates into nitrogen gas B.) A process that converts light energy into chemical energy C.) A process by which water enters the atmosphere by evaporating from the leaves of plants D.) A process that recycles elements and other matter through the biosphere

A _____________________ is a chemical substance that organisms require to live.

The ______________________ cycle is not a nutrient cycle.

Identify the nutrients described below. 1.)________________________ A key component in the formation of organic compounds, such as nucleic acids and ATP 2.)_________________________ Most abundant gas in the atmosphere; plants absorb it from bacteria in the soil 3.)_________________________ In every living thing; plants utilize it when they perform photosynthesis

A ______________________ serves as a long-term storage area for water or nutrients.

Which of the following is a reservoir for carbon and nitrogen, but not phosphorus? A.) Land B.) Ocean C.) Atmosphere

Identify the following terms associated with the water cycle. 1.)_____________________Water changes from a gas to a liquid phase. 2.)_____________________Water falls to the Earth in the form of a liquid or solid. 3.)______________________Liquid water changes into a gas. 4.)______________________Water evaporates from the leaves of plants.

Bacteria in the soil converts this nutrient into a usable form. Plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant. An animal eats the plants, and the nutrient becomes part of the animal. When the animal dies, it decomposes, returning the nutrient back to the soil. Which cycle is being described? A.) Water cycle B.) Carbon cycle C.) Nitrogen cycle D.) Phosphorus cycle

Identify the following terms that are associated with the nitrogen cycle. 1.) ______________________ Bacteria convert ammonia into nitrates. 2.) _____________________Bacteria convert nitrates into nitrogen gas. 3.) _____________________Bacteria convert nitrogen gas into ammonia.

Which of the following are limiting nutrients? Water: Y or N Carbon: Y or N Nitrogen : Y or N Phosphorus : Y or N

Identify which molecule or element is described below. 1.)__________________ Part of all organic compounds 2.)_________________ Component of bones and found in cell membranes 3.)_________________ Important component of proteins, like carbon 4.)_________________ Universal solvent

Fossil fuels are normally stored in a reservoir deep in the Earth. The carbon in fossil fuels, including coal and oil, are essentially locked out of the natural carbon cycle due to their location deep in the Earth. Humans have found a way to access and utilize this carbon. Identify a risk for accessing this carbon. A.)Scientists conclude that excess carbon will reduce the need for other nutrient cycles. B.)Scientists feel that the extra carbon will assist in plant growth. C.)Scientists are not sure if the atmosphere can handle all of the excess carbon.
