The energy pyramid below shows the energy flows from the producers to primary, secondary, and tertiary consumers in an ecosystem and the energy available at each level. How does an energy pyramid for an ecosystem demonstrate the law of conservation of energy?

• A. The energy in the organisms at each level is transferred to the level above when it is consumed.  The energy that is not transferred to consumers is transferred into heat and transformed into other forms of energy for life processes of that organism. Energy is not destroyed or created, only transferred or transformed which follows the Law of Conservation of Energy. 

• B. The energy in the organisms at each level is transferred to the level above when it is consumed.  Energy is created and transferred which follows the Law of Conservation of Energy.

• C. The energy in the organisms at each level is transformed to the level above when it is consumed.  Energy is destroyed and transformed which follows the Law of Conservation of Energy. 

• D. The energy in the organisms at each level is lost to the level above when it is consumed.  The lost energy is transferred into heat. Energy is not destroyed or created, only transferred, or transformed which follows the Law of Conservation of Energy.

One of your cells has taken in a sugar molecule from a cookie you ate at lunch. The sugar molecule contains atoms of carbon. Which best explains what will happen to the carbon after your body processes it?

• A. It is recycled by the body to create CO₂ which will be stored for later use.

• B. It is destroyed as the body breaks it down to use for energy.

• C. It is returned to the environment through CO₂ or the decay of organic matter

• D. It is transformed into sugars which will be broken down and used for energy by the body.

The nervous system is organized into two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is the processing center of the body and consists of the brain and the spinal cord.

The diagram shows the two main parts of the body’s central nervous system. According to the diagram, which statement best describes the brain?

• A. It is made up of several types of tissue.

• B. It is made up of several types of organs.

• C. It is made up of identical cells that work together.

• D. It is made up of identical organ systems that work together.

Tanya wrote the names of the five levels of structural organization. She wrote them in order from the smallest structure to the largest structure. Which of the following lists is correct?

• A. Cells, tissues, organ systems, organisms, organs.

• B. Cells, tissues, organs, organ systems, organisms.

• C. Tissues, cells, organ systems, organs, organisms.

• D. Tissues, cells, organs, organisms, organ systems.

SC.8. E.5.9

One of Earth’s characteristics is that it experiences seasons. Higher temperatures result in summer and lower temperatures result in winter. Why does the Earth experience seasons?      

• A. Temperatures on Earth vary from one location to another, causing seasons.

• B. Cloud cover is heavier in the winter, blocking radiation from the Sun and creating seasons.

• C. As Earth revolves around the Sun, the hemisphere that is tilted toward the Sun receives more direct sunlight, causing seasons.

• D. Earth’s orbit around the Sun is elliptical, and Earth is farther from the Sun in winter, resulting in seasons

The diagram shows Earth in its yearly orbit around the Sun. During the year, places in the Northern and Southern Hemispheres experience seasons because of the tilt of Earth’s axis. Which statement correctly identifies the seasons in the Northern and Southern hemispheres when the Earth is at Position D?

• A. It is summer in the Northern and Southern hemispheres because the Earth tilts as it rotates around its axis.

• B. It is winter in the Northern Hemisphere and summer in the Southern Hemisphere because the Earth is tilted on its axis.

• C. It is spring in the Northern Hemisphere and Fall in the Southern Hemisphere because Earth is farther from the Sun than it is at points A and C.

• D. It is summer in the Northern Hemisphere and winter in the Southern Hemisphere because the northern part of Earth, titled toward the Sun, gets more of the Sun’s energy.

 Mary’s family lives near the beach. Every day there are high tides and low tides. Mary notices that sometimes the high tides are higher, and the low tides are lower than they are at other times. She realizes that this happens in a predictable pattern. What causes the highest of high tides and the lowest of low tides to occur?

• A. The season changes and the temperature differences affect the water levels.

• B. The Sun, the Moon, and Earth are lined up in a straight line.

• C. The Moon is in the first-quarter and last-quarter phases.

• D. Earth's axis changes the direction in which it is tilted.

In science class, Sue and Jamal are learning about Earth’s spheres. Today they learned how the five different spheres interact. During the lesson the teacher gave the students multiple scenarios such as; how hurricanes form when warm moist air over water begins to rise, how there are plants and animals living in the ocean, how plants absorb water through the roots, and how weathering and erosion shape the Earth’s surfaces.  Which statement best describes what they learned about the interaction of Earth’s spheres?      

• A.     Weather is an interaction between the hydrosphere and the atmosphere.  

• B. Life in the oceans is an example of an interaction between the biosphere and the geosphere. 

• C. A plant’s need for water is an example of an interaction between the biosphere and the cryosphere.

• D. Weathering and erosion is an example of an interaction between the hydrosphere and the cryosphere.

Danielle designed an experiment to test the effectiveness of a new brand of fertilizer for houseplants. She spotted two identical plants in identical pots with the same type of potting soil. She added the recommended amount of fertilizer to one plant, using the other plant as her control. The plants were given equal amounts of sunlight and water each day. She measured the plants’ height every two days. After 10 days, she concluded that the fertilizer improved plant growth.  How could Danielle have changed her design to include repeated trials?

• A. tested two different levels of fertilizer.

• B. measured plant height every day for 10 days

• C. used four plants instead of one for each treatment

• D. measured plant height every other day for 20 days

Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30 second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. Which component is missing from Carmen’s experiment? 

• A. question

• B. hypothesis

• C. control group

• D. description of the experiment
