During photosynthesis, plants convert energy from the sun into chemical energy. Which of the following best describes this energy transformation?

(a)  

• Light energy to thermal energy.

• Light energy to chemical energy.
• Chemical energy to light energy.

• Thermal energy to chemical energy.

In an ecosystem, how is energy conserved when a predator eats its prey?

• The predator gains all the energy the prey had.

• Energy is lost as heat and through metabolic processes.

• Energy is transformed into potential energy in the predator.

• Energy is completely converted into chemical energy in the predator.

An incandescent bulb placed in a closed circuit works by allowing electrons to travel through a very thin piece of wire in the bulb. The bulb will then give off infrared radiation. This is an example of

• kinetic energy being transformed into potential energy.

• electrical energy being transformed in heat and light energy.

• magnetic energy being transformed into electrical energy.

• electrical energy being transformed into mechanical energy.
