Which statement accurately describes the energy needs for photosynthesis and cellular respiration?

• Solar energy is needed for cellular respiration but not for photosynthesis.

• Chemical energy in the form of glucose is needed for both cellular respiration and photosynthesis.

• Chemical energy in the form of glucose is needed for photosynthesis, and solar energy is needed for cellular respiration.

• Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.

As part of the nitrogen cycle, animals acquire some amino acids by doing which of the following?

• Breathing air

• Eating plants

• Drinking water

• Producing waste

Which of the following explains how water undergoes a change of state in one stage of the water cycle in order to move from the ocean’s surface into the air?

• Liquid water that is heated by the sun becomes a gas and rises.

• Gaseous water rises as it is cooled by the ocean.

• Liquid water that is heated by the sun condenses into rain.

• Gaseous water collects in drops of fog above the ocean’s surface. 

The 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?

• 1. X: Respiration

  Y: Predation

• 1. X: Adaptation

  Y: Decomposition

• X: Fermentation

  Y: Nitrogen fixation

• X: Decomposition

  Y: Respiration

The diagram below represents the nitrogen cycle in a student’s aquarium. Ammonia, nitrites, and, to a less 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 be the student add more of to help remove nitrates an improve the natural cycling of nitrogen in this aquarium?

• fish

• plants

• nitrobacter

• water

The pictures show a sidewalk at three different times on same day. The changes were caused by weather. Which table best describes the changes that mostly likely occurred between 6:00 a.m. and noon?

• 
• 
• 
• 

Atmospheric 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 moved by the wind toward dry areas.

• It is incorporated into the exoskeletons of flying insects that eat plants.

• It is inhaled and exhaled by birds roosting in trees during rainstorms.

• It is carried by rain to the soil.

What would be the most likely effect of a wildfire that burned a large area of a forest?

• More sugars and starches would be available for animals in the area

• The availability of fossil fuels for use by industries in the area would be reduced.

• Less carbon dioxide would be removed from the atmosphere in the area by plants.

• An increase in animal respiration would increase the release of carbon dioxide in the area.

The diagram represents a cellular process.

Which Molecule is a direct product of this cellular process?

• Glucose

• Phospholipid

• Insulin

• DNA

To study the water cycle, students add ice cubes to a glass of water. Ten minutes later they observe the glass. On the outside of the glass, students see drops of water. Which statement explains the students’ observations?

• Water vapor has become liquid water

• Solid water has become liquid water

• Liquid water has become water vapor

• Solid water has become water vapor
