Which of the following provides an example of how energy is changed from kinetic to potential energy?

• A cell phone transforms the chemical energy in its batteries into electricity.

• A tree uses the sun's energy to transform water and carbon dioxide into glucose.

Which of the following statements explains why an energy pyramid generally has more producers than consumers?

• Energy is lost as it moves through each trophic level, making less energy available to higher-level consumers.

• When a producer is removed from a community, all the organisms that eat that particular organism plus the organisms higher on the food chain will be negatively impacted.

• Consumers at higher trophic levels have more energy than consumers at lower trophic levels.

• Almost 90% of the energy in the first trophic level is transferred to primary consumers.

Which of the following helps to explain why the amount of energy available to an organism decreases as it moves up trophic levels?

• The inability of the organism to digest certain tissues from organisms in a lower trophic level causes the energy to become fuel for decomposers.

• An organism uses some of the energy for life functions.

• As energy is transferred, some is lost as heat into the environment.

• All of the above
