Cycle shown in this picture.

What is the nitrogen cycle?

Cycle shown in this picture.

What is the water cycle?

In order for a biogeochemical cycle to function properly a. There must be a perfect balance of energy and matter b. Matter must be recycled continually. c. The amount of energy must exceed the amount of matter in the system. d. The amount of matter must exceed the amount of energy in the system.

What is b. matter must be recycled continually.

Where large amounts of Nitrogen (N 2 ) are located.

What is the atmosphere?

Nitrogen (N 2 ) can be used in any form by plants and animals without being fixed. True or False

False It must be fixed first.

Name the three ways that nitrogen may be fixed?

Lightening Industrial Biological

Why is nitrogen essential to life?

It is essential to life because it is found in amino acids, nucleic acids, and ATP.

A. Atmosphere B. Nitrogen Fixation D. Nitrogen-fixing Bacteria G. Nitrification K. Denitrification

Snow, sleet, and rain are examples of _______.

What is precipitation?

When water is lost from leaves what is it called?

What is transpiration?

A water saturated zone of soil and rock is called a(n)

What is an aquifer?

The water cycle is also know as the ______ cycle.

What is hydrological cycle?

Match the terms to the cycle letters. 1.Evaporation from ocean F 2.Precipitation over land A 3.Precipitation over ocean B 4.Transpiration C 5.Seepage from ground D 6.Runoff from surface E

What are macro and micro nutrients?

Macronutrients used in large quantities ex. Carbon, hydrogen, oxygen, nitrogen, and phosphorus. Micronutrients used in small quantities, ex. Iodine, iron, zinc, others.

During this process carbon is released back into the environment as CO 2. Hint: You are adding CO 2 to the classroom right now.

What is respiration?

During this process plants take in CO 2 and release O 2 while making sugar.

What is photsynthesis?

Give three examples of how people are adding more carbon to the environment?

Cars, industrial plants, making electricity, and many others.

Match the terms to the cycle letters. 1.Photosynthesis 2.Atmosphere 3.Respiration in plants 4.Decay 5.Detrius Feeders

Match the terms to the cycle letters. 1.Photosynthesis B 2.Atmosphere A 3.Respiration in plants D 4.Decay H 5.Detritus feeders I

Why is it difficult to integrate nitrogen gas from the atmosphere into the nitrogen cycle of the biosphere? A. Nitrogen is not very abundant in the atmosphere. B. Few organisms can directly utilize atmospheric nitrogen gas. C. Most plants do not require organic nitrogen compounds for survival. D. Oceans quickly absorb nitrogen gas. E. Living organisms quickly absorb nitrogen gas.

Living organisms quickly absorb nitrogen gas.

Which of the following is known as the sedimentary cycle because its reservoir is sedimentary rock? A) carbon cycle B) hydrologic cycle C) nitrogen cycle D) phosphorous cycle

What is phosphorus?

Phosphorus is found in ______ and _______.

Rocks and Soil Unlike nitrogen and carbon it is not found as a gas

The _____ is the primary producer in the phosphorus cycle. The phosphate is concentrated in plant tissues, and then the plant is consumed by an animal.

Plant

What is different about the phosphorus cycle as compared to the water, carbon, and nitrogen cycle?

The atmosphere is not involved in the cycle.

In order to obtain phosphorus it must be ______.

Mined
