Multiple Choice

What are the two main processes that store carbon underground and release carbon dioxide into the atmosphere?

• Biogeochemical processes

• Human activities

• Photosynthesis

• Respiration

Multiple Select

This diagram shows the carbon cycle. Which of the following represents what is happening with the arrows labeled C.

• Fossil fuels from the ground provide energy in the form of carbon to the factory.

• Carbon in the form of dioxide is removed from the atmosphere, since plants perform cell respiration.

• Plants and animals die and then decomposers, break down dead organisms adding carbon to the soil.

• Carbon in the form of dioxide is removed from the atmosphere, since plants perform photosynthesis.

Multiple Choice

Imagine a farmer is concerned about the health of his crops and learns about the nitrogen cycle. What is the significance of denitrification in this cycle?

• It helps in the formation of ammonia from nitrogen gas

• It aids in the conversion of ammonia into nitrates

• It releases nitrogen gas back into the atmosphere from nitrates

• It increases the nitrogen content available to plants

Multiple Choice

Why is phosphorus essential to organisms?

• It helps form important molecules like DNA and RNA

• It is a source of energy

• It aids in photosynthesis

• It is a building block of proteins

Multiple Choice

Which of the following statements about the phosphorus cycle is true?

• Moves through the food web and returns to the soil during decomposition.

• Phosphorus leaches into groundwater from the soil and is locked in sediments.

• Both mining and agriculture add phosphorus into the environment.

• All of the above.

Multiple Choice

Discuss the role of human activities in altering the phosphorus cycle.

• They have no significant impact

• They decrease the amount of phosphorus in the soil
