- Q 1/6Score 0The carbon cycle includes processes that release carbon into the atmosphere and places that act as carbon reservoirs. The diagram below shows both major processes that release carbon and major carbon reservoirs. Which of these disruptions would cause an excess output in the carbon cycle?29Increases in marine biotaA thickening of ocean sedimentsA reduction in the use of fossil fuelsThe destruction of terrestrial biota

- Q1The carbon cycle includes processes that release carbon into the atmosphere and places that act as carbon reservoirs. The diagram below shows both major processes that release carbon and major carbon reservoirs. Which of these disruptions would cause an excess output in the carbon cycle?Increases in marine biotaA thickening of ocean sedimentsA reduction in the use of fossil fuelsThe destruction of terrestrial biota60sBIOL.12d
- Q2The diagram below represents the nitrogen cycle in a student's aquarium. Ammonia, nitrites, and, to a lesser degree, nitrates can be harmful to fish. The student wants to keep the nitrogen in this aquarium cycling normally without having to continually change the water. Which of the following should the student add more of to help remove nitrates and improve the natural cycling of nitrogen in this aquarium?NitrobacterPlantsFishWater60sBIOL.12d
- Q3The diagram shows the flow of organic molecules through an ecosystem. One process that occurs in this ecosystem is labeled X, and another process that occurs is labeled Y. Which two processes are identified by the labels X and Y?X: Fermentation Y: Nitrogen fixationX: Respiration Y: PredationX: Decomposition Y: RespirationX: Adaptation Y: Decomposition60sBIOL.12d
- Q4Atmospheric nitrogen has to be combined with other elements, or fixed, in order to be used by plants. Lightning is one way that nitrogen is fixed. When lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. In what way is most of the nitrogen fixed by lightning made available for use by plants?It is incorporated into the exoskeletons of flying insects that eat plantsIt is moved by the wind toward dry areasIt is carried by rain to the soilIt is inhaled and exhaled by birds roosting in trees during rainstorms60sBIOL.12d
- Q5This diagram demonstrates why the ocean is a large carbon sink. An increase in the amount of carbon dioxide in the atmosphere can cause atmospheric temperatures to increase. Which statement explains how this could affect the ocean as a carbon sink?Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas.Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperatures would cause ocean temperatures to increaseLess atmospheric carbon dioxide would be available to phytoplanktonLess carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean60sBIOL.12d
- Q6As part of the nitrogen cycle, animals acquire some amino acids by doing which of the following?Breathing airProducing wasteEating plantsDrinking water60sBIOL.12d
