1. choose the correct answer.

holding a ball is an example of what type of energy?
kinetic energy
potential energy

Explanation:

• Question 9:
• Plants are autotrophs that use sunlight to perform photosynthesis and make food (glucose). Animals are heterotrophs and cannot make food from sunlight. They eat plants (or other animals that have eaten plants) to gain energy.
• Question 10:
• Kinetic energy is the energy of motion. When a ball is held, it is not in motion. Potential energy is the energy stored in an object due to its position. A held ball has potential energy (e.g., gravitational potential energy if it is held above the ground).

Answer:

• Question 9: Plants use energy from the sun to make food, and animals eat the plants and gain their stored energy.
• Question 10: potential energy.
